TTI 3mm pads will fit the IPSC gauge.

You can try... Before you do, try doing couple of burpees with a holstered pistol

Make sure that one of your screws is holding the mount, and not bottoming out in the frame. You'll spot a blind hole for one of the mounts

They work great after you swap out mags, hammer, sear, disconnector, all the springs, and the mag catch

You're in for a ride... Cast frame, decent slide, cone comp, potmetal small parts, and loose fit. Metal grip is nice, moulds for the plastic ones are clapped out, so mags fall out. SPS mags are OK for 38, s#!thouse for 9MM.

No spacers needed in Atlas mags.

170s. I'm too dumb for different length mags

170s. I'm too dumb to keep track of different mags

I used Atlas for 9mm without any issues, with various projectile profiles. Anecdotal evidence in my part of the world has MBX as flawless in 38SC and occasionally needing minor tweaks for 9mm.

Pro tip. Atlas tubes for 9mm, and MBX for 38.

7lb recoil spring?? This isn't 2011 land dude. At best you'll eat slide stop pins, and at worst the barrel recoil lug itself. There's a reason why they come with 14lb from factory.

Roughly this: Prep brass. work out OAL for the barrel/projectile combo. load N sets of 10 rounds in .2 grain increments shoot said rounds from rest, over chrono, for groups (yes I'm lazy) pick the best group that makes PF pick recoil spring for said load ??? profit

Atlas mags are the tits for 9x19. Did you notice that they stamp 9mm on them? Use MBX for for the boomer round.

+1 for brake cleaner. What worked for me; Light synthetic oil. Yes, 0W motor oil works. Yes, it'll come out the back. It's supposed to Cleaning snake through the barrel after every session Bottle brush through the magwell after every session Brake cleaner when it gets super dirty
