Mark IV mods... what are the most popular?

I just bought a Mark IV Hunter and am wondering what the most popular mods are. I'm adding a picatinny rail and reflex sight, and am considering the Volquartsen trigger upgrade. I would like to find some great grips, but haven't found anything yet.

FWIW, I put 120 rounds through her today and she stove piped 4 times. I'm hoping this is a break in thang, but if not, I will need to correct it ASAP.

I put on a picatinny rail and mounted a Vortex Venom red dot. Also put the Ruger wood grips on it. I've been thinking about the volquartsen trigger but that will be later

Volquartsen Trigger Kit will help you a lot.

Get some CCI Mini Mags to break it in. 500 round of high velocity ammo should do wonders for your functionality. My friends Hunter model shoots everything he's tried.

Yeah, I'm so close to just ordering it. Feel like I should shoot this stock for a bit first.

I've been using Federal AutoMatch Target Ammunition 22 Long Rifle 40 Grain Lead Round Nose rounds in my 10/22. They seem to be fairly accurate in my rifle, but I'm not sure they're the best for my Hunter IV. I noticed I'm shooting just a tad left and low by a 3/4" @ 5 yds.

I use the Federal Auto Match now with no problems. When my gun was new I had jams with it. It needs to be broken in.

Now I can run a box with no problems, then I clean my gun and it continues to work.

Thanks! That's good to know. This is the first new pistol I have ever bought. I know that there is a break in period, but this is my first experience with it.

I've put nearly 1,000 rounds through my MKIV 22/45 Lite. Just last night I finally felt like the bolt staying open after the last round was being more consistent. Probably the first session that's it's worked correctly more times than not.

But I'm still having issues with ammo. I shot 80 rds of CCI Tactical (1200 fps) last night and had 8 FTF. The magazine or bullet tip would be bent or banged up.

I switched over to Federal Auto Match (1200 fps) and had 6 out of 100 FTF.

Guy next to me handed me 5 rounds of CCI Stingers. I loaded those first w/ 5 Federal rounds on top. When I got to the Stingers wow! Those things are awesome. At 1640 fps I didn't have any issues with those rounds.

I thought the CCI Tac and Federal were decent rounds to be shooting. I think I'm going to pick up some CCI Mini-Mags and give it a solid session after a good cleaning. If I'm seeing the bolt not staying open after the last shot, or these numbers of FTF I'm going to contact Ruger.

These numbers shouldn't be consistent with these pistols and ammo right?

I should add that I put on a TK Victory trigger and extractor.

Also similar FTF numbers with Remington Golden Bullet ammo.

there are some decent youtube videos regarding cleaning and modifying the magazines. I did this after my first 500ish rounds (I had 10-15% ftf jams)
after working on the magazines it did reduce below 5% failures...

gonna go through em again...
still, after loading 6 or more rounds into the mag, and pulling down on the spring. it still doesn't sharply snap back after releasing...

but very, very few failures when using the cci mini mags...

as far as other mods go, many are doing the triggers, sights and grips...

I just finished shooting mine for the first time.

I put 100 rounds of Federal Premium (didn't know I was supposed to shoot CCI only).
I wanted to shoot more, but had to check out my home defense and CC guns too.

Out of 100, there was only 1 stovepipe. The bolt locked back on empty every time.

The worst issue was when I couldn't "rack the slide" to clear the stovepipe.
Then I remembered to pull the "bolt" back. Hey, I haven't shot a .22 since the sixties.

After reading all the "break in" issues on this forum, it looks like I got a good one.

Check out TandemKross and their upgrades for the Mark IV. I ordered the "everything kit" for mine and although I had some shipping problems their stuff is top notch. Actually shot it some this weekend it it's quite impressive how well the trigger kit works. I don't know how I lived without the charge ring on the back of the bolt, no more pinched fingers!

Love the halo ring. I might add that later.

Congratulations on your new MKIV. It sounds like you are on the right track in mods that you are considering. Volquartsen accuracy kit and possibly new grips are a good place to start. Also, for breaking in the new pistol, a couple hundred rounds of quality CCI high velocity or equivalent ammo will go a long ways towards the break in process.
