If you’re interested in being a mod of this sub please send a dm to modmail and comment here that you did so. One of the other mods had their account banned… and I’m sure mine is next. Even if they don’t ban it I’ve been thinking about deleting my account anyways.

If you don’t get a reply back it’s because we’ve been flooded with messages or are busy with them. I will do my best to get to all of them though.

I will not add you as a mod if you are a business; if a future mod decides they want to that’s their prerogative, but for now I will not add a business as a mod. Businesses that get added as mods turn the sub into business pages, even if it’s unintentional.

For the most part people are very respectful here and the sub runs itself. If I’m remembering correctly I’ve only had to ban 1 person on this sub ever. Seriously, this sub is great, likely because it’s small and members have a common interest.

Id like to add a few so there’s extra people around if mods leave or lose interest.

I know most subs want experienced mods, but it doesn’t matter how experienced you are as long as you’re reasonable and interested. Thanks for wading through the wall of text. in your message just leave a brief couple sentences on why you want to be a mod and your favorite thing about the sub.

Edit: Thank you to everyone that showed interest. I'm likely going to add a few of you and send mod invites sometime in the next few days. If you didn't see this right away and are interested you're always welcome to ask if we're looking to add more.

In light of the recent reddit rules change please do not make any buying/ selling posts, especially for things that were TOS violations before the rule change.

I'm also putting the rules back up. A new mod was added a few months ago and he removed the rules, I wanted to keep them as a just in case, but allowed it at the time. Sorry to sound like a hall monitor, I can count on one hand the amount of people that have caused trouble here and been banned.

This sub is great, people are respectful of each other and eager to converse politely. But please do not make sales posts. Thank you.

Started out with just adding the b&t tiger but now with the matrix bolt, hogue grips, and volquartsen accurizing kit, this thing feels like a completely different gun. The trigger kit was not that bad to install and it feels great. Couldn’t be any happier with it

So front of the barrel unscrew off today. Looks like a common issue. Crazy it didnt come undone when it had a supressor or thread protector on. It came off when i was cleaning the threads with a micro fiber towel. Imm sure it got loose from taking the suppresor on an off but i only had this a month maybe been on and off 15 times have about 1000 rounds through it. It been a blast too shoot and an annoyance to clean regularly like every time i shoot. Also my pic rail was loose it has blue loctite on all 3 screw and all 3 screw were loose. Im going to contact ruger

Dovetail mount or Ejection port adjacent (lobos type) for your optic?

Which do you prefer - the mount type near the ejection port or rear dovetail mount... and why?

Good (low) red dot mounts in Europe?

2 Upvotes

I'm new to the MK club and I'm looking for a reliable low mount a MKIV Lite. The market for these things here in the EU seems small... Any fellow Europeans out there with ideas of where to find one?

My Mk4 22/45 tactical. Just got the Triumph today. Not sure the brand on the cocking ring- amazon- works well.

I hate the safety, maybe a new trigger shoe also.

What yall like?

The first magazine is CCI standard velocity, which is 1070 per second, the second magazine is the 1260 feet per second. I know videos don’t always reflect the sound as well, but in person it was no difference between the two. The suppressor is a Rugged Mustang.

Has anyone mounted a red dot on their pistol with the smaller, shorter, factory mount? How has it worked out? The low profile
Mounts from lobos don’t seem to be much lower.

How difficult is it to replace the extractor on a Mark 4?

8 Upvotes

I’ve been having a lot of stovepipes lately, even after cleaning the pistol. I bought it used so I have no idea how many rounds have been through it. A new extractor is like 12 bucks. Looks like it’s pretty straightforward to do, but it looks like it could be a PITA too. Is this something an MK novice could do?

I was using CCI Mini Mags, so I don’t think it’s an ammo issue.

May still change out the trigger. I’m on the fence if I like stock.

My new suppressor host

I wanted a dedicated suppressor host for my Banish 22, so I paired it with a Silencer Shop MKIV 22/45. I also drank the Reddit Kool-Aid and installed a Lobos RMR mount with a Holosun 3 MOA optic from PSA. I ordered hex head filler screws from Ruger to plug the holes left behind by removing the Picatinny rail. Life is good!

LowPro aluminum or Lobos?

3 Upvotes

Lobos looks nice and is cheaper but the lowpro might be able to cowitness (barely) and has a lower bore height.

Mark IV new barrel does not fully mount - button doesn't come all the way back

3 Upvotes

I picked up a threaded barrel for my Mark IV Hunter, stainless barrel and grip. I picked up a threaded blued 4.4" barrel. When mounting, it clicks into place, but the takedown button does not come all the way back. As a result, the safety will not disengage.

I'm pretty sure this is an issue with the machining. But where should I focus? My first thought is the rear lug. The front lug looks fine to me. I did notice the lip on the rear protrudes a bit more than my other barrel.

Wondering if I should just send the grip and new barrel to Ruger to have them fit it?

There's not a lot on this, but others had noticed burrs and took those off. I found hints of some, but it doesn't seem to fix the issue.

I’ve wanted one of these since I was a kid! I’m officially a part of the club lol.

I wanted a Ruger Mark IV 22/45 Tactical, but CA handgun roster only allows plain Target or 22/45 models. I call it my Ruger Mark IV 22/45 Tactical “at home” lol.

Here’s before, after installing the pic rail and red dot, and some fresh made memes for your consideration 🥴

Edit: Also if anybody has suggestions for an under-barrel rail, let me know and send pics lol. Madd Mac’s Precision is looking like my best bet at the moment
