Run it past these guys before you sell it. An odd bunch, sure, ;) but they do know it all.

That is often too small of a chamber, or too sharp of an edge at the opening to the chamber. You can check the former by removing the barrel and trying to press rounds in with your finger. The latter will show up as scuff marks on one side of the brass in mild cases, right up to shaving brass in extreme cases. You can check this by reassembling the gun and chambering rounds from the magazine in the same manner it would if it were cycling. If they won't fully chamber, put a bit of force on the slide. Extract them and see if one side is getting scuffed or shaved. If they are, very slightly break the sharp edge of the chamber. A small cone shaped abrasive stone, like from a Dremel tool set, does a good job. Turn it by hand in a pin vise or something. It doesn't take much.

Do you mean you are going to try an new recoil spring?

So it is not going fully into battery?

After you first try Jeff's suggestions, You might try different ammo. I have different luck with different ammo. And I have to shoot with a new ammo for awhile on the tight chamber match guns like a Hammerli 208S before they function reliably, even if I go back with a ammo it was use to but shot another in between.
I think it is a function of the external lubrication difference of .22 long rifle ammo.

That pistol would be gone from my safe, if the manufacturer can't fix it. Life is too short to use broken stuff. Just trade it in for a revolver. If that isn't your thing and it has to be a pistol, then I agree with the Ruger Mk1-4 recommendation. The latest version seems to be much easier to R&R and clean. That hunter pistol posted is beautiful, but it is a bit of a brick IMHO (I used to own the MK3 version and traded it for a waterfowl gun I actually use).

^^^^ Yep. I have a Ruger LC9S purchased a few years ago (my first & only 9mm) after trying my uncle's, and deciding I needed one :). Well...the one I purchased sucked and was deffective...out of the box. FTF on at least 30%....

The idiot at Cabella's said they don't take spoons back :(

You wanna bet?

GOML :)

....."MY" LC9S has never ftf....

try a little firmer grip and stiffer wrist.
I have to tried to relax my wrist and grip with my 9 and let the gun "move" a little more. not good.
the shots can go high and it too will jam.
you have to do a death grip but perhaps more in support from the wrist.

^^^ if that's for me....nope! Spoon was obviouly deffective, to me, and the idiot at Cabella's once he broke it down also :).

Me: I need to return a deffective spoon that's ftf on about 20/50...I see why.

Him: We don't accept returns (I knew this to be a lie....I had returned a Henry .22 before)

Me: I want to speak to a supervisor.

Him: I am one.

Me: Then I want to speak to the store manager.

Him: Broke the gun down and saw what I did...it should have never been sold...obviously deffective

I hope he liked "crow"....of course he was important enough to delegate the "normal return" to a nice kid for me :)

What a prick...him & me (if I have to be)...

This is a very competitive market these days. Really, if the manufacturer cannot fix it and make it right, there are plenty of others to choose from. If they are not going to make that choice for you - from their own inventory, after trying to fix "yours", it's pretty easy to tell them to keep it and you will shop elsewhere.

That is certainly one approach. For me, if I really like the gun, I'm willing to fiddle with it a bit. These are pretty darn simple mechanisms. If the basic design is sound (and the Buckmark is very sound), it's going to be some simple little thing that is probably pretty easy to fix.

I've only sent one gun back in my entire life. I bought a 4 1/2" stainless Blackhawk in .45 Colt (what else?) for my oldest son on his 21st birthday. The front sight was clocked over at 1:00. Not a "home repair" by any means. Ruger's customer service was outstanding. It spent more time in transit than in their shop. I can't say enough about those guys.

I skipped that whole thing and bought the conversion kit for the P226...

Though now that I want to teach my daughter I'm thinking I should have one of those.

I'm old skool Jeff...I wuz already apprehensive about buying a spoon JMB didn't design...."striker fired"....wtf :)? It wuz going back after only half a box of break-in...a disposable, but gotta be reliable spoon....so it went back.

Love it's replacement....flawless.

What ammo have you tried?
My P22 often won't cycle with any sort of sub-sonic or low velocity round.
Federal seems to give me lots of trouble.
Remington golden bullet is decent but a little dirty and generally 1/100 FTF.
CCI Blazer seems to be the most reliable of the pinking ammo I've tried.
