I got my buckmark in February, put thousands of rounds through it so far. At first things were going fine, but now reliability has gone into the shitter. I get lots of light primer strikes, now the slide locks open randomly mid-magazine. At one point the magazine disconnect became messed up and the trigger wouldn't reset, though I think that has been fixed now after I took teh grips off and made sure everything was ok inside. The rubber cover on the slide stop fell off, which is odd cause I never used the slide stop, always racked the slide. That wouldn't cause the slide to randomly lock open though? I just had a really frustrating plinking session with my gf last week when the gun kept malfunctioning every magazine. Gave it a real good cleaning and took it out again for another 200 rounds on my own this week and it didn't matter, still light primer strikes and the slide locking open. Any idea what could be going wrong or is it time to ship this off to Browning? |
| As far as light primer strikes, you might want to make sure the barrel screw is tightened (on the front of the frame just below the barrel). This screw is either a slotted set screw (old style) or a allen set screw. I know just about every screw on mine works loose after a few hundred rounds. I like the pistol, but using that many screws to assemble is not good. (And yes I put lock-tite on all of the screws, but they will still loosen after time). |
Yeah I've been having the top sight come loose a lot too and had to always tighten that down, very annoying. I'm on the verge of just trying to get it fixed and then selling it, it's so low cost though it's almost not worth sending back even.  Will have to see if that barrel screw has come loose, it looks locktited in from the factory and I never touched it, will have to try, thanks |
The newer Buck Mark barrel screws are indeed loctite-ed (new word?  ). But I'm not certain which year they started doing that. At least 2-3 years ago.The slide locking- It sounds like you got that fixed. It's easy for the scissor spring 'leg' to fall out of its' little hole in the slide lock if the left grip panel has been removed, or if it became loose. Nothing else will hold it in place. The rear sight base screw loosening under fire- Many Buck Mark owners will order a batch of the cone-star-washers, and replace them periodically. This will lessen the problem, and eliminate the need to use loctite. Obviously, they lose their effectiveness with wear/use and by being crushed with over-tightening. Personally, I never experienced the problem in the dozen or so Buck Marks I've owned, but I did the majority of my cleaning with a blasts from an airhose & and a boresnake.... mostly disassembling them only for trigger work. On the rest of the malfunctions, I recommend a thorough scrubbing, with special attention to the chamber area. Good luck, and keep us posted please. |
| Thanks, I will have to do some chamber scrubbing I think, the rest is spotless right now, and get some of those washers, that makes sense. Hopefully that will get it running fine for next week, my buddy who has been living in japan is coming back for a visit and bringing his japanese girlfriend, need to show her American gun culture! |
| For the light primer strikes, you might want to consider taking the slide off and giving the firing pin channel a good scrubbing. I did that with my 5.5 target and was really surprised how dirty it was and how much resistance all the crud was giving the firing pin. |
This. |
Are you refering to the small 1/2" x 1/4" plastic buffer that is held in by the recoil spring/recoil spring guide? It's #25 in the picture. You are going to have to remove that to take the slide off of the gun. The firing pin (#32) is held in with a roll pin (#33) through the side of the slide.  |
| I must have a newer version than that schematic, there is no roll pin through the slide. Rather the slide is machined inside and the guide rod and firing pin are in a plastic insert that fits within the slide. It didn't look like something I could easily disassemble last time I looked at it, but I'll have to try again after work tonight |
It's super easy dude, just use your intuition and dive into it. If you've never taken that out then you've actually really cleaned your gun since you've owned it. Your firing pin is going to be super gunked up in the channel it rides in. You're going to have to fully clean any .22lr from time to time to keep it running 100% so it would be a foolish move to sell it cause you don't want to take the time to clean it. My .02 |
I'm kind of curious about this newer design, could you be troubled to take a picture of it? |

Wish I had seen this yesterday! This link to a manual for the buckmark shows some of the firing pin assembly. I took it down and cleaned out the firing pin channel, which wasn't really dirty inside at all, I think most of the carbon builds up on the part of the slide where the firing pin goes through more than in the overall channel. Also tightened up the barrel, which did come loose apparently. Will have to replace those washers another time, but hopefully this will keep it running well when I take some newbies shooting. Thanks for the help all |
