I bought both the Tapco and Krebs trigger/hammer retainer to see what all the hype was about and see if I wanted to install them into my Wasr and PAP.  I noticed that on the Tapco the bottom edge of the retainer did not want to slip into the groove into the trigger pin and on the Krebs the cut out in the front did not want to partially slide into the hammer groove on the pin.  I have read some reviews on both of these and some say you have to partially fit them in certain areas.  Is it just the Tapco trigger/hammer pins that are the issue since they both came from Century and maybe I need to buy different trigger/hammer pins or do these retainers require moderate fitting?  For now I will just put the Crook back in both of these for the time being.  The reason I bought these is because there is slight trigger pin movement in both the Wasr and Pap and I have heard that can cause mushrooming in the receiver over time.  Thanks.

There shouldn't be a problem with the pins themselves.
I have had issues with the Tapco retainer fitting and will no longer use it. The other one should work fine. Sometimes I have had a problem getting it to seat around the hammer pin. Just keep fiddling with it and it will seat.

I think I will go ahead and get the Power Custom retainer and see how that works.  I messed around more with the Krebs last night and it is far better than the tapco one(which I just tossed in the trash) but the trigger pin was still rotating a full 360 with that in.  It doesn't rotate that bad with the crook though and I am sure the Krebs was put in properly.

Is there a problem with the factory wire retainer? All AK factories have been using them since the AK was invented. Sure, if you routinely remove the trigger parts as part of the cleaning process, the retainer would make re assembly easier. But in over 10 years & many AK's, I've never had to remove the FCG. I feel this is like the "should I use a recoil buffer in my AK" question. So many people have answered that they never come that way from a real AK factory, & I feel this should be the same response with these retainer plates. Many have to be "fit" to the gun. Who wants to buy a product & have to modify it to fit? A wire retainer will last a lifetime, & never have to be modified to fit. Just ask Vlad at a real Russian armory. If a wire retainer is good enough for real military full auto AK's, it's good enough for us.  GARY  N4KVE

That's what I thought initially but you know how the internet commandos say you have to get XYZ and it seemed that the crooks were failing people on different forums and places on the internet that I read.  I will just stay with the crook and thanks for your input N4KVE.

I've used Tapco and RSA/Power Custom and never had any problem with them.  The Chinese type wire retainer is simple to install and I prefer it to the crap retainer that Century rifles have installed.

Forget the Chinese wire retainer. The hammer and trigger pins will rotate just the same as with those worthless retainer plates.

Unless I missed something, if the pins are secured as to not walk out, why is rotation a concern? Is something damaged by the pins spinning?

Some people are under the impression that if the pins spin, the receiver will wear out.  GARY  N4KVE

I will also rotate the air in their tires for a small fee. Don't want that stale air in there, and you can't put a price on safety can you?

It's for the children after all.
