Lately I have been trying to move it toward some direction.
Right now I have most of the necessities covered. Couple CCW, something for up close, something for far away, something cheap to shoot, and something rimfire.
I love variety but I have found that the more I get, the more out of hands things get. I needed to be mobile so I had to slim down my collection a little.
My method right now is "the list".
If I want a gun, it goes on the list.
On the list right now are...
DSA STG58 FAL - I ordered it today and it should be here in a few weeks.
GP-100 - I have one on layaway right now with almost 3 months to pay it off.
Last is either going to be a commander sized 1911, a Glock 19 or 23, or a highly customized SP-101.
Although I don't strictly stick to this, it at least keeps me from buying on impulse. I at least have to think before I buy something.
Like Dionysusigma, I have had alot of guns bought on impulse. Aside from gifts, I started out with a Ruger Single Six. Bought a Kimber 1911. Sold the Single Six and bought a S&W Model 18. Bought a 4" 686. Traded the Kimber to a P-225. Sold the 686. Bought a S&W M-60. I could go on but it is all too much to try and keep straight. I have to behave myself of this will never end. I now mostly look hard before I buy and plan to keep the ones I have now and buy from now on for the most part.
I have also found it best to accessorize a gun with most everything I am going to need before I move on to something else.
