View Full Version : Full Auto RIA
8th December 2005, 18:19
I became very popular at the range today when my RIA Full Size switched to 3-shot burst. Interesting and fun in a Robocop way to say the least.....In all seriousness though, I stripped the pisol and it appears that my searspring and sear aren't getting along well (or maybe getting along too well :scared: ). They just don't seem to be fitted well. This is my first 1911 so I'm a bit of a noob when it comes to smith work. I was hoping you guys could steer me in the right direction as to what I need to fix. I found a Wilson Combat Sear on Brownells that I'm going to replace definitely but should I also replace the searspring just to be sure? Any recommendations on brands and where to purchase? Thanks for the help and sorry no pics.

first i would search the tech part of this forum for the function check..(tried to link, didn't work) and follow the function check. if the hammer follows the slide back, strip the weapon down and remove the sear spring, i believe it is the middle leaf you want to bend forward slightly....put it back together and do another function check.

Your new sear will need to be fitted to the hammer.........then the thumb safety fitted to the sear. Then the sear spring adjusted properly to get everything in harmony..........
If you're not sure how to do this, have a qualified 'smith do it........or you're liable to end up with the same 3-shot burst 1911.

Agree with Wichaka, if you are unfamiliar with the fitting process of hammer, sear, safety, and spring, let a qualified gunsmith do it for you. And if it is botched, you may end up with a 3 shot burst pistol or a full automatic pistol.

Try putting some more pressure in the middle leaf of the sear spring and see if that helps. Bend it a little towards the frame.

Thanks for the suggestions. One of the range officers and I took it apart after my fireworks and we noticed that the searspring was slipping off the side of the sear. We did bend it a bit, reassembled the gun, and then did a function check. The hammer remained in place when we racked the slide a number of times after depressing the trigger. I'm just unsure as to whether this quick fix is a permanent fix. I'm inclined to say no as the searspring appeared to be too narrow for its place and the RO said the sear itself didn't appear to be fitted well. I know that Armscor sends these out with a lifetime warranty and I believe this should be covered. However, I don't know if they'll replace anything if the pistol appears to be functioning normally at the time; leaving me out $50 shipping and 3-6 weeks without my 1911. What do you guys think? Thanks for the help!

The way I test for hammer follow is with the mag out, chamber empty, and I only do this about 6 times (don't make a habit of this as it will eventually damage the hammer and sear), lock the slide back, then drop the slide stop and see if the hammer stays put 6 times and don't touch the trigger at any time while doing this. If the hammer follows the slide, then you still have a problem.
