[Current Manufacturers of Aluminum Frames?]

L-10 Firearms out of CA. Used to. Idk if they still do. 

[Anyone know how to disengage a slide stop lever?]

I’ve had good luck with option 2 as stated above. 

[Most aggressive SS grips.]

VZ Tactical II work well for me. 

[Main Spring Housing Tool]

+1 @davsco where’s your sense of adventure OP??!! Use a punch and swear words like everyone else LOL JK! That’s a pretty cool tool!

[Dawson DPO as aftermarket cut?]

staccato offers the service according to their website. 
 

 

[2011 that runs well on a factory ammo]

If you find a used one, a Staccato XL in .40 will eat whatever you throw at it. 

[Staccato xc magwell]

Akai and Dawson will fit. 

[Staccato XL now IDPA ESP legal]

1 hour ago, davsco said:

damn, at 50 yds i can barely see the target, that's some TIGHT shooting!

LOL, I learned how to shoot pistol from the bullseye crowd when I was growing up… I don’t like working fundamental, but they’re important. 

[Staccato XL now IDPA ESP legal]

I have one for USPSA limited. It’s a solid pistol all the way around. Everything’s tight and holds 3” off-hand at 50 Yds if I’m doing my part. Only thing I changed was the magwell. 

[2011 140mm 9mm Magazine Setup]

Personally, I don’t think you can go wrong with either option for a 2011. Big thing between TTI and Dawson is size. They are both easy to disassemble and work on without tools.

[2011 140mm 9mm Magazine Setup]

TTI 4mm base pads with grams springs & followers seems to be the norm. That’s gets you 20 reloadable in a .40 prolly 23-24 in a 9mm.

 

Good luck. 

 

[2011 build]

Warwick Tactical makes some good stuff too… and you can get the slide barrel and frame fitted like Brazos. 

[which cz should I pick???]

TSO all day!

[Shadow 2 SA, or TSO (first version)]

I don’t think you can go wrong… I have bigger hands and have shot a TSO and a Shadow 2. Both guns fit my hands well, meaning I can access the safety, mag release, and slide lever without manipulating my grip. There is a difference circumference wise, but it is minimal and I think you’ll be happy with either. Kinda depends on what division / game you’re looking to play. 
 

good luck!

[Ultrasonic Cleaner]

I detail strip my pistols and put everything but the tiny parts in there. The model I have had several settings with 480 seconds being the longest. I run it with heat for 480 seconds. Take it out and let it drip dry. Then run a bore brush down the barrel and patch till clean. Wipe off the excess and back together the gun goes. Pretty streamlined and simple. I suppose you could forgo the extra barrel cleaning but I like clean lands and grooves lol

[Ultrasonic Cleaner]

Hey there,

 

I bought this off Amazon on a whim and am thoroughly impressed. I’ve had mine for a while with no issues whatsoever. Very simple to use and it also has a heater to help with cleaning. I use Lucas ultrasonic cleaner solution inside (usually have to replace every 3-6 month depending on the time of year). This is as cheap and easy as it can get.

[Anyone know where to find Shield S 15 mags?]

You can order them from their website. I’ve never seen them in stock. But, they allow back order. When I did it, I got mine it approximately 2 weeks. I legit think they can’t keep up with the demand and just ship out as they get materials. Hope this helps!

 

 

[Favorite mag button?]

SVI tear drop. I didn’t notch the grip tho, I took metal off the back of the tear drop until it functioned. Then, I locktited the screw to the mag catch.  Works like a dream. 

[Tso mag well]

Without taking it apart or looking at it, I would assume you could peen the track it sits in to keep it tighter. I used to do that trick with M1 garlands go keep them tight. Your other option is to drill and tap a screw if there’s enough meat to do it. Good luck

[Staccato frame question]

What did you think of the pistols? Which was your favorite?

[Magazine extensions- what are you using for Glock G35?]

Dawson Precision makes a great +5 as well. 

[Bad JUJU?.... Glock's & metal mag releases]

MBX makes metal Glock mags that would go with the metal magazine release. They’re predominantly for PCC, But a Glock mag mine the less...

[Optic Plate System Options?]

I would think they should, they make plates for Staccato/STI. Those all use the DPO/DUO optic plate from Dawson. 

[Staccato C question?]

Correct. The new mag releases are specific to the pistol. 

[Optic Plate System Options?]

EGW makes one that fits into existing dovetail cuts... IDK if your going that route or not. Then, CH Precession Firearms (CHPWS) also makes mounting plates / cuts slides as needed. 
 

Good luck!
