Storm Lake 9mm conversion barrel

Sunday, at the range, I shot my M&P40c with the Storm Lake 9mm conversion barrel, and it went REALLY well.

The 9mm accuracy was every bit as good as it was with the stock 40 caliber barrel. I also had zero malfunctions after shooting 250 rounds of relatively cheap ammo. (124 Grain Aquila rounds, made in Mexico, and 115 grain Federals, the cheapest stuff on the shelf at Wal-Mart).

I don't want to sound too exited about this, but I'm beginning to think these conversion barrels are the best thing since sliced bread. I feel like I basically just purchased a new M&P9c for about $130. (ok, I did spend another $39 for the 9mm magazine)

Thank you, good to hear. I too have nothing but good experiences with my S/L barrels. Well worth the money spent

I've got a 9mm SL for my 40c. And like you, LOVE it. I actually use my barrel everyday for carry. Would rather have the capacity over size.

I got lucky and bought my SL used for $80!

I keep hearing these good reports. I own both calibers in the M&P but it might be nice to just take one gun to the range with an extra barrel.

Mine was fitting a bit TOO tight when I first purchased it. Worked fine the first few rounds, then as things heated up, it started to lock the chamber closed after the last round (if there were still bullets in the mag). It never failed to fire...

I called Storm Lake and sent it back with the slide and the factory 40 barrel. They took a little flash off of it, and shaved a bit off the area around the locking lugs I guess... Anyway, it's perfect now, more accurate than my factory 40 barrel.

Customer Service was exceptional, and turn around time was days. I spoke directly to the guy who was working on it. He had a co-worker bring in his personal M&P 40 to test it with my slide before shipping it back.

Buy with confidence.

I posted this in the full size MP category also, didn't notice it in the range report. I have a M&P 40 with the Stormlake 40-9 conversion barrel also. Probably 300rds through it. First two mags had 2 feed issues, but that's it since then. Mostly Winchester white box 115 grain I think. I'm really low and right with everything. I've put the 40SW regular barrel in and I'm much better. Only modification is the Apex FSS aluminum trigger entire kit. I can't imagine that would make me low/right with it? All you guys are accurate with it? What distance? I was at 10-15 yards only. I am a terrible shot, but still. Is this something they can "fix" at SL or do I need to try other rounds? What grain do you guys use?

Anytime you change anything it can affect the point of impact, changing to a different brand of ammo in the same bullet weight can change the point of impact, or changing the bullet weight can change the point of impact, so its no surprise that switching calibers would change the point of impact.

Glad to hear about the Storm Lake conversions working well. I've been kicking around the idea of getting a full size "something" to shoot along with my Shield 40, and start debating on whether it should be a 9, which I don't have, or another 40, or even changing brands. Then I read something like this, and it brings me back to my senses. Go with the first plan, FS 40, add 9 conversion and mags, and done.

Stormlake VS KKm

Is there any difference between the Stormlake barrels and the KKM barrels?

KKM's barrels do have a much higher attention to detail given to them; they look so much better and their barrels are button rifled while Storm Lake barrels broach rifled.

I have two Storm Lake barrels, my only complaints are the craptacular laser engraving, the lackluster brushed finish and some rough edges, otherwise they work great.

Considering the prices are almost exactly the same I would recommend KKM over SLB. I got both of my Storm Lake barrels on clearance, but if I had to purchase them at full price I would have gone with KKM. Another advantage to KKM is one can order directly from their website, while finding Storm Lake Barrels at retailers can be like looking for hens teeth.
