Hi all,

New to this forum and to .22 rimfires, so please excuse the naive questions.

The pistol shoots great, but I notice a heavier trigger weight on the last round. It's not terrible, but it's noticeable. Is there a way to remedy this issue? Also, any other thoughts from the experts here on suggested reliability work would be greatly appreciated. I have plenty of tools, but no drill press.

Thanks!

Welcome to Guntalk-Online

Have not heard of any thing like that. The only thing I can think of is that maybe the magazine is backing out. There is a nub on the back of the trigger that lifts the mag if it's not fully seated. Normally you will notice a 50# trigger so you know something is wrong before the mag ever seats. But this would be on the first round and the mag is backing out. A lot of users replace the trigger with a target trigger which has adj for pre and post travel. These triggers do not have the nub. It does not hurt to grind it off. To me it useless since I was never able to seat a mag with it.

As far as reliability most are good right out of the box. The weakest link would be the stamped Extractor, but would not worry with that unless your getting stove pipes. Some think the LCI is a problem. It only becomes one if it get gummed up. If you can push it out and it springs back freely it's ok, once it gets gummed up it will be sluggish.

There are a lot of upgrades you can do if you want to improve the already proven design. Grips, VQ sear, Clark MKII Bushing, VQ trigger to have the adj outside.

Welcome to Guntalk-Online!

I have to agree with Blue on the upgrade recommendations. I believe this is the first I've heard of that particular type of problem with the trigger pull on the last shot. This is a Mark III 22/45 that we are talking about, right?

Thanks for the input guys (and the welcome!). This site has been extremely helpful to me.

Yes, it's a brand new MkIII 22/45. The pull seems slightly heavier at the last round, but since neither of you know of something obvious that may be causing it, I'm wondering if maybe it's my imagination. BTW, it's no so heavy that it bothers me; it's just slightly more so.

I meant to say earlier that I have a VQ extractor on order from Rimfire Sports. I had heard the factory extractors are not the best. Also, when I took the gun out of the box and field stripped it, the first thing I did was pull out the LCI (thanks again to the instructions on this website). That said, I have about 500 rounds through it so far in the last few days and have had only one ejection issue that I attribute to the ammo (Remington "Golden Bullet" plated). The CCI Mini-Mag is been perfect.

Sound great. I wouldn't worry about replacing that extractor until you start having problems with it. Then you can go with a VQ.

Good idea, Bullseye. Doesn't make sense to replace the part until it starts to malfunction.

From what I've read in here so far, it looks like a detail cleaning is a good idea at around the 1,500 round interval. I typically use Ballistol on my guns, but I've also heard that lighter fluid on the trigger parts is a good idea. I'll do some searching, but if you have any thoughts on this I welcome them.

Thanks again.
