1911 slide stop
Just picked up a sistema colt. It appears to be in very good shape, but I am not too familiar with 1911-style pistols. With the magazine in, the slide, when pulled back with an empty mag, stays back. When the mag is out, however, and I push up on the slide stop with the slide back all the way, it barely holds the slide. It doesn't take much to have the slide spring shut. It appears that the indentation on the slide where the stop holds it is slightly worn. What is the best remedy that you know of? My thought is to take a file to the indentation (or a roto tool) and square off the indendation, but I don't want to go that far yet.

Believe me, I don't want to grind any more than the poor pistol wants me to grind on it! 0 -
as stated, that area of the slide is sensitive and should be dealt with by a 'smith.' that area is also prone to cracks from the stress of catching the slide on the last round. it can wear out. you need to check the slide release lever too. its the cheaper and easier place to start. change it out and see if it helps. if not, have a smith do some work to that slide notch.

Don't recall ever seeing that problem in inspecting thousands of US Army 1911s.
Be aware that squaring off the slide stop notch will be moving the slide forward in the locked position. You wont want to affect the reliability of picking up the first round from a new magazine.
As has been mentioned, examine the slide stop fit in the slide notch for wear or an incorrect mating angle and alter the slidestop to accommodate the slide notch rather than the other way around. A new 1911 slidestop might work better.0 -
v35...the one gun i saw this crack on was my colt commercial circa 70's. it has about 20,000+ 'if not more' rounds threw it. all ball 230. i know this is a strange crack. i've only seen 2 in my days. my luck, one of them was my gun! i agree with you on filing anything. even though that area is so small, so much depends on it. such is pistolsmithing! take care. 0 -

Steel has the property of notch sensitivity. A sharp notch concentrates stress by several hundred percent. For stressed steel parts, good design practice includes a radius (polished if possible)at the bottom of a notch or abrupt change in crossectional area.
Fatigue failures are progressive cracks which start in such areas.
Steel forgings having proper reduction ratios in the forging process
have a higher fatigue life than cast parts or parts made out of bar stock. Colt has traditionally made these parts from forgings but I'm suspicious they may have tried castings to cut costs since some new steel casting methods were developed at that time.
I would hope Colt made good on the cracked slide.
That Systema Colt slide stop notch should have a radiused & polished base to it.0 -
sounds right v35, i just hope some of the guys up in the NEW colt factory here in conn, are old school. i kinda doubt it. afterall, ever since the factory went PC with the public, im sure all the equal rights groups demanded their inch of the factory and could care less about QA. but hey...thats a political forum discussion for another day. i hope our reader is taking good notes! 0
