try to shoot this gun with buffer.
i use on mines buffers in 9mm with factory ammo.
we have in club 2 tso with over 35k each with no problems, but in 9mm.
why not.
u can order this model. only u need to mention this in the order : stock2 AUS model with 4.75 " bull barrel.
i ordered one like this for somebody from the club.
all inside parts sear,hammer, disco and new trigger with flat/curve inserts are bul designed parts much better than from extr. engineering parts.
inside /outside finish much better than sti dvc line.
i have pic.of competition guns from 1992 european champ. Spain
first open holster in the world.
1911 guns in 38cal many.
german made 1911 stile gun like phoenix trinity honcho . 10mm cal 6" long slide.
cz long slide 6" barrel
tanfoglio with aimpoint
jericho 941 open gun
and i saw few open glocks that shoot major .
most 9mm guns shoot major loads in this competition as i remember.
most optic was aimpoint and tasco pdp 3
most guns was 1911 single stuck .most of them cal .45 clark and wilson models with front sight on comp.
i used in 86 wilson model 9mm . and from 86 compensated 3 chambers cz75 with peter sthal 5.25" polygonal barrels.
i saw Jery Barnhart with collimator sight in late 80's. i started to use tasco pdp2 in 1992. best scope in the world.
about compensators or muzzle breaks in 30's US gunsmith made custom 1911's for known american gangster.
it was bushing type muzzle brake.
exactly .that what u need to fix.
basically it's almost the same like mine with few differences . i made 10mm dia. hole for recoil spring with 90deg wall and 60 deg chamfer.
and i use larger dia. guide rod.
