It is possible to get a 9L slide and barrel to convert a standard size gun to a L variant. I'd suggest looking up http://www.speedshooterspecialties.com. Email them and get on the waiting list for a 9L slide and barrel. The complete upper to convert your standard gun to the L should be under $400

The 9L is most definitely the way to go. Aside from the longer sight radius, the 9L slide is slightly heavier and that translates to lesser felt recoil as well as faster return of the sights on target after each shot. I've shot them side by side and the difference is tremendous. The M&P naturally points for me with the long slide, however it doesn't point so straight with the shorter slide. Pair up the 9L with a set of Warren Tactical sights (mine has the FO front and plain rear) and you're looking at a seriously winning combination.

The Pro sear is shorter than the standard, so it's more likely to have the dead Sear issue because of the way the sear rocks on the pin. We've found that the standard size Sear Spring is simply too small to have enough power to make the Sear stay in the up position to catch the striker. That's why the MA guns have better luck, the Sear plunger and spring have enough mass so the Sear doesn't over come them via inertia.

I'll snap some shots of my 9L tomorrow morning.

The Sear housing block is wearing. Remove your slide and look at the rails....you'll see clear wear lines from material being removed. Scott

I've done exactly that on more than one Sear, it does help some, but you have to be careful about it ad make sure not to take too much off. I'd suggest taking .005" off, that will give you .008" more engagement on the Sear. After the .005 I'd only go another .001 at a time if that.

The dead trigger issue seems to currently be the weakest point of the M&P. IMHO it's a problem with the sear not sitting high enough up to catch the striker on the return of the slide. This is caused by a metallurgical issue that wasn't foreseen by the engineers that designed the gun. The Melonite surface on the slide is just too hard and the Sear Housings are the wrong material and aren't hard enough to stand up to the stress of the slide running across the surface with so much force. As I understand it, the factory has been working on this issue, but I don't know their solution just yet. We've been drilling the Sear Housings and installing MA compliant Sear Plungers and a different spring to fix the issue, so far we've had good luck with that solution. Scott

A little thing I like to call the telephone. Thanks, everyone loves a smart arse. I dont have that option during work hours. Emails or other online communications works for me. guns@apextactical.com

Millisec, That's some good advise. Good lookin out for your fellow M&P owners. Scott

The frame for the thumb safety models is different from the non safety models. You would have to machine away part of your internal frame to make it work and I would definitely not advise that. Scott

I'm with Sfinney on that. Go with the Dawson Warrens. The Dawson glows great in decent light and paired with the Warren, it's the best combination I've ever used. I shot that combination on my 220 and 229 for IDPA a few years in a row and I loved it. The 17 lb spring will really help you with the Initial DA pull. If you decide to stick with the Sig and want action work, look up Grayguns.com They do awesome stuff with Sigs.

Sorry bro

Thank you for your kind comments. The reduced Striker Block Spring is designed to help smooth up the operation of the Striker Block. Being slightly lighter, it reduces drag on the upward movement of the Striker Block to reduce felt disengagement of the Striker Block while the trigger is being pressed. We are working on a billet striker and trigger bar. They're a bit farther down the road, but they're on the drawing board. Scott

The 4lb trigger pull is not what's recommended for Duty/Carry. We're recommending the full DCAEK that produces a 5lb pull for Duty/Carry applications. Scott

The competition spring kits will be available soon. 20-24oz isn't likely, but 2-2.5 is doable.

When I was at GGI, I used to weld on the Custom GGI magwells and blend them in (Torie does an awesome job of that now) on the P220ST frames. We had talked about doing mag wells for the 226, but we did not have them off the ground by the time I left. I'm sure somebody else's mag well can be used, Ive just never looked into it. Scott

I used a Dawson Ice Magwell for the Para Ordnance. I did some milling on the inside of the magwell to open it up to fit on the outside of the grips. I stuck a set screw on the front to keep it in place on the frame where I ground a divot for the screw tip. On the back end I tapped the holes for screws and ground divots into the grips to retain the mag well at the back end. I had to take some material off the inside of the magwell to accommodate the magazine bodies and the stop plate on the big sticks. I'm not sure how well it's gonna work with factory mags just yet.

In my experience it works with all calibers.

We've found that it's the size of the port holes in the barrel and their location that makes the most difference. After calibrating the port holes to reduce muzzle flip to an optimal degree, we set up the comp. accordingly. It's all in the routing of the gasses. It's the Mach cone that we're capturing to create the upward blast through the comp. Mike Voigt is the guy to talk to about comp design. Multi port comps sell so well because they're more pleasing to the eye as opposed to working best. This gun started out with a massive 3 port comp. as you can see in the following photo. The recoil and muzzle flip was still so much that it was uncomfortable to shoot for all of us at the shop. When I came to Apex from GGI, I reduced the comp to 2 parts and stuck in one port hole in the barrel, it helped but the second hole really knocked down the muzzle flip. Randy recommended opening up the comp into one big port and that really killed the over recoil impulse. All I can say is that it works.

With the pair of inline ports in the barrel, the comp is best with one large chamber.

Thanks guys. I'm gonna do a write up about the build just for fun. I'll tell you, it was a hell of a project and I couldn't have done it without the help and advise from Master Pistol Smiths Bruce Gray and Randy Lee. Scott

I almost exclusively shot Sigs. Specifically my P229 and P220.

Thanks, I'm glad to still be around. You might contact CPU Fixer about them...if they're the big sticks, he may want them. Scott

Hey guys, this is Scott Folk from Apex Tactical, I'm the putz building this gun for CPUFixer. The comp has one large port and the barrel has 2 other in-line ports as well. With the ports and comp setup the way they are, this gun is one flat shooter. Anybody else wanna know anything about the gun?

Sounds like the sight was over hardened during the heat treating process. I would think that Dawson would replace it for you if you called them about it. If the sight was fitted too low with a lot of stress between the dove tail and the top of the slide, I can see the snap of the slide slide cycling causing a stress fracture that would snap it off without warning.
