Here’s a deep dive / review / look into the USPSA Open Division race gun that I’ve been shooting for a year now. It’s built a decade ago by a local GM. I bought it used from a fellow shooter here in the PNW. Here’s the breakdown :
DAA Foldable Jet Wings
KIDD Blast Shield
38 Super Comp Ultimatch bull barrel
SV (Old STyle) Compensator
EGW Extractor, ejector & lockwork
SV Frame with stippled polymer grip
Infinity TriGlide widebody trigger bow
Infinity long flat trigger insert
Infinity round commander hammer
SPS magazine 170mm (w Grams guts & 4mm bolens) 29rnds
SV Magazine 170mm (w Grams guts & 3mm bolens) 29rnds
STI 140mm (w Grams guts & 7mm bolens) 22rnds
I bought three used magazines from a fellow shooter on Brian Enos Forum. One SV 170mm Mag tube, one SPS 170mm magazine and a STI 140mm Magazine. I also ordered three Bolen base pads from Shooters Connection and a EGW Magazine Gauge to make sure my magazines are under the maximum length limit for the USPSA Open Division.
Two 3mm and one 7mm for the 140mm STI Magtube.
The SV Tube that I bought came with a Dawson SNL +1 base pad which does not fit the gauge, so I had to swap it with a 3mm Bolen Basepad. (One down)
the SPS magazine was really short, compared to the SV tube, so even with a 4mm Bolen Basepad, it still is under the maximum length. (That’s two legal)
The third one was my old SV 170mm magazine that came with the gun, it about a 1/1000th of an inch longer so I had to file down on some areas to make it shorter a little. I had to do the same with the black SV mag tube above. so after fiddling around a little, here are the results. I manage to make 28rounds fit, but can’t get anymore. Some folks on the forums can fit 30, I have no idea how that’s done. Perhaps I need to tune the springs or something.
The last bit was the STI 140mm mag tube. It came with an STI basepad, I tried fitting on the Dawson SNL+1 basepad and all I got was 21rounds. After replacing it with a Bolen 7mm basepad, now I get 22 out of that magazine.
here’s all of them in a row and the current ammo capacity, I tried but I couldn’t get more than 28rounds to fit reliably.
There, I’m ready to go. armed with 108 rounds of .38 Super Comp. Now all I need is my rig.
