Dont know where some of you live....but I never seen the sheriff in person. I pay for the suppressor, get the finger prints done by the sheriffs secretary and she hands them and forms with pics(done at any walgreens) off to the sheriff. A few days later I get a call saying the forms have been signed. Thats when the wait begins.





Its not hard, but waiting sucks.





Ask your local class 3 dealers about your local sheriff and if he will sign. You can make a trust which avoids the sheriff signature and finger prints. But costs a few more bucks to have the trust written.







My biggest complaint above all other's is the bs I hear from folks who havent done it. Bet the atf sits back and laughs. Ive been told so much nonsense, and most of it is widely regurgitated through the internet.



I didnt join this forum to talk suppressors. Got a 9mm pro showing up Wensday.....woot woot



P.S. love the above video and the little kids responses. Sounds like me minus the high pitched voice

Stainless,



Not only crimson trace, but one of a kind IR crimson trace. Generally I hate lasers, but its the only option for shooting under NODs.











I just picked up some FSS kits, really looking forward to those.



Great information on this site. Thanks to those who keep it up.



ETA: here is a video on my Tirant 45 on my Glock (Before I saw the M&P light). I converted a TLR-2 to IR and that is what is depicted. (Glock 21 with TLR-2IR)

Also, maybe not the best place for this, but if anyone cares, I took an X400 and TLR-2 completely apart. The short version is that the surefires are built better. Here is a link to my poorly written review.

I can't speak about the M&P specifically as I'm now shopping for my first one (which is how I discovered this great forum), but I've been using an AWC Abraxas on several of my glocks for over five years now; and the fact that it allows the use of the sights was one of the reasons I went with it. The M&P sight height may be different enough that it's not do-able; can't say for sure, but even with small, factory triangle sights, the glocks do still clear the supressor. It actually also allowed unobstructed use of one of those internal guide-rod lasers, but I've since changed back to factory guide rods for durability reasons.

This is the 3.3-oz (sans grease) Abraxas, on a little glock 26 with my old-technology norrell .22; the little 9mm suppressor is about the size of a .22 suppressor of the 1990's. They've come a long ways internally and the abraxas (and some others as well) are surprisingly small & unobtrusive nowadays:

I hadn't heard of these until I watched Gabe Suarez pull one out of a compact flashlight case (about 1" ID x 5 1/2" long) and screw this tiny suppressor onto his 9. I thought it was a .22 or something, sure enough it was a 9mm Titanium Abraxas. Sound suppression was pretty good, might not be the quietest of the bunch, but much better than average. I think it was Gabe who described the sound as a hand clap (optimistically). Put it this way, I'm not ready to trade in my 40 Osprey quite yet.

Seems like Gabe had a little trouble getting the slide to lock back, have you experienced this? My guess, he went too heavy on the recoil assembly?

I am still looking, but haven't yet found a set of purpose-built tall suppressor tritium sights that will work on the M&P slide, like those available for the H&K and Sig's.
I might have to fabricate some.

My interim day / night sighting solution for the SpecOps with a suppressor.

On a new gun, it's finicky; but on a well-broken-in gun it's smooth & all functions work as normal. Bear in mind the only pistols I run this one on are glocks (19's and 26's), and glocks are fairly notorious about being hard to make reliable when suppressed, unless you use a suppressor with a booster (nielsen device). And also, when running suppressed I use almost nothing but 147 and 158 grain bullets, which help increase the recoil impulse which helps with functioning when suppressed.

All that said, I still can't vouch for it allowing the use of the sights on an M&P; still shopping for my first one at this time. I switched from 1911's to glocks in the late 1990's for open, on-duty carry, and while they're objectively great guns, they're like an ak-47 to me - they work fine, but I just don't really 'like' them. That's why I'm looking for an M&P now; I want something with glock capacity and simplicity and hopefully reliability, without that goofy glock trigger. At my age (past 50), I've finally reached the level of crotchety that I'm going with "what I want" at this point. My wife thinks it's my version of a mid-life crisis - but rather than trading in my practical truck for a corvette, I'm doing it with my guns instead of vehicles. Maybe she's right. Don't much care; that's the beauty of embracing the crotchety...

More porn then...

I only have three suppressors is all, the abraxas, that norrell-design .22 pistol, and an M4-2000 for AR/CAR use. But the abraxas is by far the one I use most; it's just very versatile.

This is a puma 1892-design 16" carbine in .357 magnum that I had modified to accept a suppressor and a red dot. I've had more than one person use the word "abomination" when seeing it for the first time, but it's HUGELY versatile and practical. Running just-subsonic 158-grain handloads, it's got roughly the muzzle energy of a .45acp govt model shooting 230 hardball, but basically zero recoil and is still quieter than my gamo pellet gun. And even those that hate it when they see it don't want to give it back once they use it. It's been a phenomenally handy little setup for me:


I don't know if that pic got stretched a little when I cleaned it up or if it's just the angle, but the gun's not as long oal as it looks there; so for comparison here's a better pic. Notice that even with the suppressor attached, it's still only the same size as a standard 10-22. (This was before installing the scout mount):


This is a cut-down, threaded & suppressed single-shot, that's even quieter to operate/reload stealthily than the levergun. Barrel is still over 16" so no class-3 issues with it. I'm in a very rural area (north-central Arkansas) and this is a sweet little 'critter-getter' setup; largely for nuisance animals around the property. It's a .357 magnum, but I mostly use .38-special-level loads in it to keep it subsonic & quiet. Same abraxas suppressor:


Without suppressor, it looks odd, but still over 16", and still as powerful as a .44 magnum handgun when using full magnum loads:


And..... the fun one. An old marlin camp-9. Rear optic is a normal bushnell red dot in extra-high rings; front is a DBAL clone with visible laser, IR laser, and IR flood. Using NV headgear, the IR setup gives you basically a spotlight/laser combo, that's only visible to NV-wearers. This setup does put the red dot higher than ideal, but it's worth it for me personally to have the zero-fuss option of switching between regular optic or NV use. Sighted at 60 yards keeps it within 1.5" of POA from 5 to 75 yards; and the short ranges I use this at, the extra mounting height isn't as bad as it sometimes would be. I've switched it to extra-power recoil springs to help with heavy-bullet loads and the increased blowback a suppressor causes.

I had a 12" picatinny rail mounted when it was threaded:



With the suppressor in place:



Suppressed, it's not as quiet as the levergun with same-power loads, that's the inevitable trade-off for the faster follow-up shots of the semiauto. The blowback action makes it about as loud as a suppressed 9mm pistol; still very quiet, but not not up with the sealed-breech lever action.

Ok; that's all the porn for this morning. Gotta go help a family member do some electrical repairs at their house.


Wait - one more.... Glock 19, decked out for the inevitable zombie-squirrel invasion:

Looks like you've built quite an arsenal around that little suppressor. About how many rounds downrange.

Dang Zombie Squirrels.

Have to think. On the glocks, biggest workout they get is our annual "Guys Retreat" where about 12-15 of us older guys take 35-45 teenage boys from church on a three-day campout. We spend one of those days rotating the boys thru four shooting stations - pistol, rifle, trap/skeet, and archery - typically ten rounds per kid thru the glock with it on. Additionally, some of the old guys do play before & after, so probably 500-600 on that one day per year alone; not counting me & my sons over the rest of the year; probably another 700-800 per year is all from us. (Thru the glocks) So say 1200 per year over the 5-6 years I've had it, or 5000-6000 thru it on glocks to try & be conservative.

On the levergun probably another 800-1000 is all, total over three years or so. On the marlin, a little more; probably 1200-1500 or so. On the single-shot, less than 300.

So rough estimate, but I bet relatively close, probably 7000-8000 in all; and 98% of those charged with either lithium grease or at least a water dunk between magazines. Almost all of them were 147's or 158's, standard pressure.

I have no idea of the life-expectancy of the abraxas, but I'm sure one of these days it'll just wear out. That's a substantial trauma on such a small device.





And don't get me started on the zombie squirrels. They sneak up on you...

This was ~15 years ago, when on a family-member's back porch and a squirrel jumped on my back. I'm some older now, with a beard. (A largely-gray beard... )
