I have this exact same issue, but I've had to switch to left handed shooting of rifles and shotguns. The only cure I can see is to get a single trigger gun with the trigger set back as far as possible. My left middle finger gets carved near to the bone when I shoot clays left handed. I have not been able to hone my grip to where this doesn't happen.

I am 79 and have had that issue for the last couple year,.guess i am not gripping the gun correctly. Bobby

Arthritic hands/fingers is, I think, a large part of this. My left hand grip just doesn't seem to be as positive as my right. Decades of building muscle memory may play in here also. I'm guessing that if I shoot enough, which is difficult here, I will reduce this issue to a tolerable level. I just need to get out and shoot up all the 5-gal pails of reloads I've produced. I also may be acquiring a very nice, cased, single trigger G&H Francotte 12ga here soon so I can experiment with the single trigger thing. If the trigger is set back enough, it will work. I can shoot the rear trigger on any of my Parkers all day long with no issues.

Good eye! I don't know why my Uncle Irv is holding my Father's AE-Grade Remington in that picture. Irv shot a pair of early Remington Model 870s, a 12- and a 20-gauge, both with Poly-Chokes and left hand safeties.

I understand that pain very well. I try to use the tip of my finger to pull the trigger, but when shooting birds, I forget all that and just raise the gun and shoot. Inevitably, I end up pulling the trigger with the middle joint of my finger instead of the distal end. Have a big lump on my middle finger from years of doing it. Something about an old dog and new tricks.

Short fat fingers? That's my problem. I use the rubber bumpers and they work just fine for me. I put them on every double trigger gun I own before I ever shoot it; it only took it happening to me a couple of times for me to try to make sure it never happens again :nono:!

Never had that problem. Try stretching your finger out more to reach the front trigger so your not cramped when going to the rear trigger. You may be loosening your grip when you pull the trigger. Keep a tight grip on the stock so the trigger guard and hand move together during recoil.

I have big hands with long fingers so, never had the issue. A friend of mine with small hands and short fingers had Kirk Merrington bend both triggers on several guns, back and straighter, fixes his problem

Google “shotgun finger guard”. Several different makers.

Thank you for your advice . I have looked at how I grip the gun and see what y’all are talking about , I can see a trip to the range in my future .
