I've put 200 rounds through my new colt classic 45 so far without any failures. The slide stop comes out of the frame during take down easy and goes back in very easy. I'm wondering if the slide stop plunger is not applying enough pressure on the slide stop to prevent a possible failure. I also have one in 38 super in which the slide stop is not as easy to take out or place back in and I notice the plunger sticks out further in the opening which applies more pressure on the slide stop. So I ordered another slide stop plunger that's Colt OEM to see if there is a difference, what the heck the part is less than $5.00. Has anybody else had a problem with the slide stop plunger? Or maybe I don't really have a problem. Just wondering.
