View Full Version : Need Help with Slide Stop problem

April 27, 2009, 08:10 PM
I was redirectedI wrote one time before about this problem. What is happening is when I shoot my RIA 1911 A1 .45 acp , the slide stop wants to back out and it locks up the slide. It happens when firing. The slide moves all the way back and throws the empty, sometime after that before the slide can return the slide stop backs out and keeps the slide from returning completely and chambering the next round. All I have to do is simply press in on the slide stop and the slide chambers the round as normal. It doesn't happen on every shot but I would say 3 or 4 rounds out of every 7 rounds it does. I have tried different magazines and I have also tried different slide stops. No improvement. What really throws me though is that this never happened until I got around 300 rounds through it and now it has developed. I'm left handed so its not my hand hitting the slide stop from the way I grip. Can anyone tell me how to fix this or if you have experienced this and what you done to correct it? Thank you

Bearbuck to here from another thread so here is my problem. Can you help?

I sent you a PM with a link with photos on how to remove the thumb safety to inspect your plunger tube, spring, and detents.

There's several things that can cause this.
First thing to do is make sure it's not shooter induced, is any part of your weak hand resting against and putting pressure on the slide stop pin?

As for mechanical things that can cause this, overly large or out of round slide stop pin hole, slide stop pin hole is not bored straight, poorly cut or fitting of the barrel feet, poorly fit slide stop, loose plunger tube, short plunger tube pins or weak spring, slide stop pin is bent or not true.

You might want to take your gun to smith in your area and see if he can diagnose your problem.

Install a notch on your slide stop.

Another, there can be a binding happening between the slide stop and the barrel lower lugs, this can be too tight that it pushes the slide stop out during the course of the bullet on the groves.

Most of the time the cause of this is 1) a badly made slide stop or 2) a badly made frame. You should NOT need any kind of detent or notch to keep the slide stop in place if the gun maker did his job right. (FWIW, I have seen a number of RIAs and do not consider them high quality. The only advantage they have is a low price which is usually more than made up for in frustration.)
