hello.
i have a sti trojan single stack 9mm that was converted to .38super.
when i fire the weapon, sometimes the brass just falls right out of the gun and sometimes it goes where it is supposed to about six feet away.
i am using wilson .38super 10rd magazines
the ammunition i run is 135 power factor
another thing. i am using new winchester .38super +p brass and at 135pf the cases are bulging at the base. i think the gunsmith who did the conversion might have throated the barrel too much. could this be a factor?
the barrel is ramped and fully supported. i was thinking before that with the full magazine putting a lot of pressure on the underside of the slide, that might slow down the cycling slide. but the ejection is hit and miss at all times.
now when i run major pf loads the ejection has no problem at all and it land in a nice little pile about 6 feet away.
the brass is no more bulged than it normally is with the low 135pf load.
on the breech face there is a little more wear on the upper left of the breech face just above the extractor.
i am currently running an ismi 12 1/2lb spring. i use a 19lb hammer spring.
any help is appreciated, thanks.
