Chip Mcormick trigger

[10fcp]

I just received trigger and was installing it last night. I am putting it into a CMMG lower and the trigger pins won't stay put. I ordered a small pin trigger and the trigger pins just fall out once it's installed. I followed the directions and even had a youtube video going too. What am I doing wrong? do I need special pins for this? Thanks much for any advise

Is the lower brand new or older? There are 2 sizes of trigger but as far as I know the two are regular and large pins for weapons that are older and the holes have gotten bigger from wear. Most kits also come with a pin used to hold the trigger in place while you slide the regular pin in.

OP... is this what you go? A CMC drop-in unit?



If so, I think you need their special retaining pins. The drop-in unit doesn't have the spring inside to hold mil-spec pins.

The kits usually include pins with c-clips. The pins should have a groove on them to attach the clips and secure them from backing out.

It's a CMC. Stuff is supposed to fall right out.

Even the welded base plate on a 1911 8 round mag.

I have one sitting on my dining table that needs to be sent back.

I see your trigger has a similar 'feature'.

Sure makes cleaning the mag easy though.
