22lr Handguns-Reviews, Recommendations, and Trouble Shooting

1. ruger 22/45 mk iv 4"
2. Picked it via familarity - grew up shooting a mk ii a little. I use it to practice and for fun - a suppressed 22 is hard to beat for entertainment/cost ratio. Ive always figured trigger pulls are trigger pulls
3. With the vq bolt upgrades (extractor + spring) ive had none. Around 1k down range of multiple flavors. I didnt have any prior to the bolt upgrades but i just figured id add them when getting the trigger.
4. Not applicable.

I enjoy shooting mark ivs - theyre similarish to 1911s - the only drawback is the mag capacity.

I continue to feel someone would be filthy rich making lowers (that arent 600 + like tandemkross) for ruger mark ivs.
I saw a patent application a few months ago, from Ruger, for a double stack 22/45.

Too bad they wont just sell us the damn lowers.
 
1. Mark IV Standard 6". Only mods I've done are to have the back of the front sight cerakoted red, and I put on some wood grips.

2. In Canada I can only shoot it at a licensed range. It's just a plinker for me.

3. Generally bulk 22, usually CCI or Federal. I gave up on Winchester bulk ammo because I found it had about a 10% rate of duds that wouldn't fire, many of which wouldn't fire even after putting it through again hoping there'd be functional primer somewhere else on the rim. The only ammo it doesn't cycle is Norma Tac 22; I think it's because of the wax on those.

4. No reliability concerns at all. With range only use, durability is never tested except maybe at a high enough round count, which I haven't reached after probably 10k rounds or so (just a guesstimate based on typical shooting volume over several years).
 
Really torn between Hammerli H1 to stick with the 1911 style as I rotate between it and my SA 1911, or the MKIV. The amount of reported blowback with a suppressor is my only hesitation though. I will 100% be running suppressed and not having all the gas in my face is a big concern. Interested to hear if that's a 1-off, or common report on the H1.
 
As I posted above I’m a huge fan of the hammerli, but if suppressed shooting is your priority I’d get something else. Or get a hammerli for 1911 training and something like the MKIV to mount a suppressor.

I’ve never shot a flow thru suppressor of any kind but I did wonder if the huxwrx 22 flow thru would decrease the blowback on the hammerli. Any thoughts?
 
Gave the Mark IV 22/45 from above a good cleaning, re-lubed with Rimfire Remedy, and hit the range to try a few different types of ammo last night.

Did 100 rounds each of CCI Standard Velocity and Blazer, 85 rounds of Federal Champion (ran out of time)

3. Preferred ammo... don't know, but it IS NOT the pictured CCI standard velocity. Had a number of failures this evening through 200 rounds.
After cleaning & re-lube, the CCI Standard Velocity did fine. Had one failure to feed that was magazine related (first round was nose high, jammed into top of pistol, different mag than other FTF issues noted below)

Blazer had multiple failures to extract/eject, didn't cycle the slide enough.
Two failure to feeds, magazine related (see below).
Shot poorly compared to the other two. No longer in consideration for this pistol.

Federal Champion appeared to shoot the most consistent, only failure was a magazine related FTF (see below)

Also, did this happen with each of your different magazines?
One mag had multiple failures to feed (didn't advance the round high enough to strip off) with both Blazer and Federal. That individual magazine has been put on a PIP.

If you know you're going to run suppressed 100% of the time, you will NOT be happy with the Hammerli H1.

As shocked and amazed as I have been by my Hammerli H1, especially in the mechanical accuracy department, I can confirm that the blowback issue with a suppressor is real, and the pistol is very unpleasant (to me, at least) to use with a "can" screwed on. Not a deal-breaker for me, because I can't legally hunt on state Wildlife Management Areas with a can screwed on or use one at WMA shooting ranges.
 
Super interesting - I know that's good stuff, and how you described what it does on application with garage doors is interesting too. I couldn't find anything on its WD-40 web page, SDS, or TDS about its NLGI grade, but a couple of consumer websites like MSCdirect and Penn Tools list it as an NLGI 2. But a #2 is a lot heavier than a thick snot. Snot would be, as you mention, closer to a #0, or a #00. With the oils wicking away and possibly it's carrier/propellant gasses dissipating...does it get thicker after sitting for a few days?

Regarding layering it, that makes sense in theory, but the oils are going to get absorbed and/or mixed in through cycling. Of everything you mentioned, you'd probably get the best results out of mixing with ATF. Marvel is good if you need an oil to crawl deeply somewhere that you don't want to disassemble, like deep into an adjustable sight or something. But the ATF will be the slickest, by far, and probably the best weighted to mix into a really light grease for a rimfire, with that WD-40 White Lithium spray. If you want to experiment, spray some of that grease into a paint cap or other small container, and let it sit for a couple of days to see if it thickens up from losing its carrier. Depending on if it thickened up much, mix in about half as much ATF. That would be slick as hell, and probably very close to a #00.
RE the WD-40 specialist white lithium grease.

I put some down after your post to check for evap. Checked it today:
Still the same snot/mucoid consistancy.

I also cracked open the 45acp that was lubed well before the last 1911 match. Probably 700-800 rounds on it since it was last lubed. Lots of hot/cold cycles. Dust, contaminants, powder residue, etc.
I found that same mucus consistency smeared on the inside of the dust cover and slide. Looks like it hadn’t broken down or hardened.

I’m going to call it a true NLGI 0.

Next, I mixed it 50/50 with ATF, and it made a runny egg yolk consistency. So…NLGI 00?

I took my home-bru and did a quick refresh on the slide and rails of my 22lr and 1911’s/2011.
I am not exaggerating, it was genuinely eye-opening how much more slick it made those guns. Like take away the clickedy-clackety sounds smooth. It made the MP22x slide feel like a 2011.
And the 2011 felt like ball bearings. Shocking change 😮.

I’ll stress test the lube this next week on the 22.

That is awesome, would look forward to hearing about that homebrew over time in those different applications. Great to know about the WD-40 keeping its consistency, too.
 
As dumb luck would have it, ran into a fella shooting a suppressed TX22 Compact at the range (red dot, Silencerco Sparrow)... Nice enough to let me shoot it. Felt great, sounded great. Can't speak to accuracy or function with only 6 rounds on steel. So now I'm explaining to my wife why this would be a great way to drop $1k (supressor and dot included).
