Greetings, This is my first post on MarlinOwners. This is a terrific resource and I'm in awe of the level of knowledge and experience out there. Hopefully I'm not doing this the wrong way or in the wrong place. If so, I hope that somebody will point me in the right direction ... Anyway, I have a checkered stock on a recently acquired camp 9 that hasn't seen much use, if any, so is in excellent condition. The gun even had the original, in-tact, yellowish/cream colored recoil buffer - that is until after I put about 100 rounds of standard ammo downrange (50 - 115 Grain TCJ Precision Reloads / 50 - 124 Grain TMJ Speer Lawman) which, of course, cracked the original recoil buffer (just couldn't wait for the new buffer to go shoot it). There was no other damage thankfully. I've since then replaced the original recoil buffer and spring (Blackjack Buffer and Wolff 16.5# spring). I haven't shot the gun since the aforementioned recoil upgrades and I'm concerned about the stock cracking since I've read about this being an issue on these CC's. Is anyone aware of stock cracking issues happening after the heavier recoil spring and upgraded buffer were installed - or is this problem pretty much limited to the OEM designed lighter springs in combination with the OEM designed brittle buffers? I'm the type to clean and examine my firearms after each use - regardless of the number of shots fired. So I'll know if there are any new recoil buffer issues after each outing and will replace as necessary and I will replace the buffer after 5000 rounds, necessary or not, since that's the "guaranteed" life span of the BlackJacks. Thanks' in advance for sharing your experiences.
