should i buy more gun or shouldn't I thats the question ???

Al speaks not with forked tongue, IMHO.Unless there is something your current carry gun can't do for you I would hold off. Most people get into the "gun of the month club" and never learn to work any of their stuff properly. By the time you buy guns, ammo and holsters for each additional gun purchased you tend to have a safe full of unused guns and a box of worthless holsters.
And as an experienced shooter you are a knowledgeable buyer. You know where the gun ends and the shooter begins in selecting a carry gun. Too many of the new guys get caught up in the hype.I tend to take a different view of things, but perhaps that's because I'm reasonably accomplished with all my guns.
Al speaks not with forked tongue, IMHO.I think there is definitely a bit of a learning curve that we go through until we sort things out and figure out what's best for us.
I do also agree with Deadeye in that if you purchase quality firearms, you really can't get hurt, as prices tend to only climb of late. I think if we slide further and deeper into recession the used firearms prices might come down a bit, but I have not seen that happen with any of the Colts I tend to keep an eye on.
That is very kind of you to say LevelG. If I can ever assist you in locating a nice Colt please let me know, as I am always happy to help. :drinks
