I won't say my impulse buys are wack but they are definitely impulse buys. I can't remember the order but here a few.
Sig P226 Tacops- wasn't planning on buying a gun but held it and had to have it. Expensive f'er too!
H&K USP compact 9- I don't see many H&K's around my area so I picked it up. Put 50 rounds through it and sold it.
Glock 26- this was a custom pistol. Lone Wolf barrel, stainless RSA, TFO sights, 3.5# trigger, titanium plunger and more. Shot like a dream and accurate as Hell. Saw it and told the guy to put a price on it. Took it to the range the next day and another shooter saw me and offered me more than what I paid for it. Gone.
Berretta Nano- saw the reviews and decided I wanted one. I played with the trigger at the LGS and thought, it's not to bad. Wrong. There's a reason I never owned a Berretta. (YMMV)
Glock 34 & 35- both wicked accurate weapons. This was when I thought about competing a little. Bought both at the same time. I put some rounds through both of them but carrying them was a pain. (more on carrying further down).
Ruger LCR .357- I read really good reviews on this pistol. I saw a few but they were quickly snatched up. I finally saw one and instantly bought it. Trigger is one of the better ones. This was going to be my BUG. Purchased some .357 and .38's and went to the range. This little SOB kicks with the .357. No problem, i'll use the .38's. Still stings and i'm at a bit of a disadvantage already missing part of a finger. Sold.
I'm sure there's more but frankly, I can't remember. As for the carrying part? If I can't carry it comfortably, I won't own it. I am now down to my Glock 30S and a Ruger SR22 that I am teaching my daughter with.
