Hey fella's, Im new to the forum and I need some help diagnosing a couple of problems with my recent purchase. I have read the sticky post by 1911 Tuner but I could use some clarification.
SA 1911 Ultra Compact shooting 230gr FMJ round nose( Winchester, I believe )
I ran about 10 mags of ammo through it this past weekend.
First issue: The slide locks open with ammo in the mag.
Insert mag...pull slide = locks open most of the time
fire 1st round = locks always
rest of clip = sometimes locks open
I noticed that it seemed to lock open more often when shooting two-handed as opposed to one handed.
I looked to see if the rounds are pushing on the slide lock pin but it's hard to tell...any tricks to doing this? Should I use a feeler guage to check for clearance? If so, how much??
Second issue: Last round in mag (6 roung mag-SA NM blue) always jams nose up. Spring is fairly strong compared to other mags I have owned. the bullet stops with the nose caught on the top leading edge of the barrel throat with a slight overhang of the slide port covering the nose. This jam only happens on the last round. The gun has not jammed on any other rounds so far. Eject the mag and round pops out onto the ground.
Third issue: Ejector spits brass at my eyeballs. Yes, there are marks on the front edge of the ejection port- what does this mean?. OK, radius the bottom corner of the ejector...radius the end that butts up to the shell casing or radius the bottom of the face that catch's the lip of the round? Any pics of how it should look???
I purchased this gun used but in A+ shape, it showed very little wear inside and flawless outside. I have no idea on how many rounds have been through it but just looking at the internals I don't think very many.
Im not a super-technical gun guy but I do have machine shop experience so I am comfortable working on some of the minor stuff. Im thinking of changing the recoil spring and adding a radius to the ejector. Also, maybe try a Wilson stainless mag.
I appreciate any help you can give.
Thanks.
