Frankly, I am all for trading up and moving on when the time is right. Yes, I have divested of guns I wish I had not. Divested of a Mini-14 when money was tight...regretted the heck out of not having a semi-auto .223...UNTIL I bought an AR...regret over.
Divested of a GP100 and regretted that...UNTIL I bought a 627...regret over (although in this case I paid way too much for the 627 and other than 8 over 6 shots really doesn't do anything better than the GP100...trigger is better).
Divested of all my commie milsurps and funded other gun purchases. Some folks will disagree and it's up to each individual, but barring some sort of real collector or sentimental item, a gun collection is a fluid, dynamic thing.
If you could divest of the two guns you've got via private sale, save a couple bucks back, you could purchase a Glock 19, a Ruger SR9c, a S&W M&P, a good used Sig...whatever...and have a more modern pistol in a very common caliber. Gun sale regrets are not one of life's bigger regrets. I mean don't sell a Savage 99 for a Glock
...or a vintage SAA or something...but commie guns...easy come, easy go I say.
