Full auto Co;t 1911

I'm trying to learn about the 1911 by adding some "drop-in" parts. They certainly are not drop-in! Anyway I dropped in a BT grip safety, sear, disconnector, hammer, sear spring. Went to the range today loaded and fired one round, everything was fine. Loaded two rounds, first one fired just fine, and the second round fed into the chamber correctly but the hammer fell when the slide went forward without firing the second round. Everything is clean and lubed but I don't know what to look for as the culprit. I won't fire this pistol again until I fix it. Anybody got any suggestions? Thanks.

Hmmmm

Howdy,

It sounds like your disconnect may not be dropping down far enough to break the connection between the sear and the trigger. Run a quick
check. Clear the gun, and dryfire it. Keep the trigger held to the rear and
hand-cycle the slide to see if the hammer follows it down or stays cocked.

If it follows during the hand-cycle, the disconnect may be out of spec, and the slide isn't pushing it down far enough. If it stays cocked, it sounds like
either hammer bounce or the sear isn't resetting into the hammer hooks
fast enough to get a bite. If this is the problem, the gun could go full auto if the sear just barely catches the hooks and gets jarred off when the slide goes to battery.

Try bending the left leg of the sear spring forward a little to see if it helps.
Bend above the spot where the leg joins the main body of the spring. Bending at the junction can break the leg off.

Best guess without seeing the gun...The disconnect isn't disconnecting
and the sear can't reset.

Keep us posted.

Thanks John

John,

Thanks. I just finished putting the stock disconnector back in before I read your reply and it passed the dry fire test. I may put the "drop-in" disconnector back in and checking it again. I'll have my local 1911 pistol smith check it out before I fire it again. I'll also check it out by firing one live round followed with a snap cap just to be safe.

I have to say Thank You for being responsible enough to only put one round in the magazine and then test firing. I (along with everyone else I'm sure) have heard way too many horror stories about people tinkering with a pistol and throwing in a full clip to test it.

One Round Test

Amen Ron....Now tell me what you'd think about a pistolsmith that claims he's built over 200 pistols in various calibers on the 1911 platform with 3.5-pound triggers in'em, never test-fired a single one before delivery and never had one come back?

Disconnector bad

It was the disconnector that was the culprit here. Put the stock one back in and everything is functioning fine.
