Cyl. pins

therevjay · May-27-13 15:05

Has anyone else had problems with cyl. pin 's coming loose during a range session? I had it happen 3 times while firing a 50 rd. box. I'm (pretty) sure I had it firmly in place after the 2nd time, before that it very well might have all been my fault. This is with a mag, never had any problems with LR which of course produces much less recoil.

At home while cleaning I can find no sign of the dimple in the underside of the Bbl. getting egg shaped. (which can occur after a LOT of use) I tend to think it's a combo of my carelessness and the fairly brisk recoil of the .22WMR but I figured I'd see if others ever had a problem.

It happened with my new Pug this weekend. Second or third shoot , pin jumped out a little and jamed the cylinder . Pushed it back in and fired the rest ok. Only had time to shoot 5 rounds , but did not like that that happened on the first time out. Will have to do more testing when time will allows.

I had exactly the same thing happen to my mini. I was shooting Hornady critical defense. I think that caused the problem. CCI maxi mag shot fine along with about five others. I think the CD is designed with faster burning powder for short barrels. That causes higher pressures which forced the pin out about a half inch. Took it back to the gun shop and they worked on it a bit and fired about twenty rounds in the shop. No problems. I still wasn't feeling warm and fuzzy about it so I traded it in with the same dealer for a Pug.

No way a different type of ammo should cause a cylinder pin to fall out. If it falls out you have a gun problem. Larry

All magnum loads are punishing rounds for these little beautys . Why they ever came up with these is beyond me . Long rifle has been and still is the best round to use in these minis . I've said it before and I'll keep saying it , magnums were designed for actual rifle loads ,case hardened steel also . Scale these magnum rounds up to standard size handgun and you would probably be shooting 45 -70 rounds , if not longer , in that handgun , think how long that would last . Again only my opinion but give me long rifle for longevity and less problems .

This is a known problem with the other-style pins, but the new ones should be fine. If you have to rotate the cylinder pin knob into place, you have the new one. The old style just has a spring ball that would sometimes dislodge during shooting. Which one do you have?

I have the old style w/spring ball which is more prone to this problem. After a bit of thought though, I believe OV-1D to be right about .22 mag to not be a ideal cal. for these little guns.

I guess I am a bit out of touch here. I was not aware that NAA had a new style pin for the Magnum Mini. Can someone post a photo of one? I have not had any problems with my cylinder pin, but I do not shoot a lot of magnums out of my Magnum Mini. Considering the jolting recoil of magnum rounds out of my minis, I would say that if anything can vibrate loose then it will vibrate loose.

I had a Stainless Ruger Blackhawk with a 7.5" barrel in 44 magnum a few years back and the original Ruger base pin backed out with heavy loads.

I replaced the original base pin with a Belt Mountain base pin that had an Allen set screw to hold it in place against the recoil and it worked.

I personally would prefer another locking point and a pin on any NAA Revolver that stayed in place over faster loading.

Thus far I have not had the base pin back out of my Pug with either 22 long rifle or magnum loads.

MR-22, Assuming I have the "old" cylinder pin, and am having problems with the pin dislodging, do you know if NAA will replace the old pin with a new pin? From a safety standpoint, I would think NAA would treat this like a recall and replace all of the "old" cylinder pins. Thoughts?

Call customer service.

Go to the pictures of NAA revolvers on this site. You will see some have a pin you push in to release the detent & some have a piece that has to be pulled down & twisted to release.
I don't know if the regular revolvers can be upgraded but the older Black Widows can. Mine had the push type & the cylinder pin would jump forward almost every time. It couldn't just be pushed back in. It caused a bad jamb.
I returned it to the factory & they upgraded it to the new style for free (except shipping). I don't know if they replaced the barrel or just cut the groove in the old one.

My BW has the pull down and twist cylinder pin. So are you saying NAA can put that same type of cylinder pin assembly on a 1-5/8 Mag? Currently, my Mag has the push pin and pull cylinder pin. To this point, I have not had this type of pin disengage while firing.

The pins Mr 22 is referring to are on the BW/Mini Master style guns, not the mini mag. The pin on your .22 mag should not work loose. Call NAA customer service, and I suspect they will simply mail you a replacement.

I also have the older type cylinder pin. My problem is just the opposite. I have a hard time getting the pin out for reloading.

I would call customer service. Although I understand the point of view that the magnum loads are much harsher, NAA offers these cylinders for this specific and intended purpose. We could only assume the firearms have been tested rigorously for use with these rounds, To deny yourself the full capability of the weapon to solve the issue is a temporary work around at best and not the actual solution. Call NAA. These revolvers come with lifetime warranty and NAA's exceptional customer service will take care of the issue.
