For 2010 I would have to say my RRA AR. I purchased from another INGO member, had been wanting to get another AR and have taken advantage of haveing one again.
This year was a good year for purchasing guns for me. I started the year with a Savage 19 .17HMR, which I love shooting. Then in March, bought a S&W M&P 40 w/night sights. Later on came a Walther PK380 one for me and one for the wife, a Saiga 12 shotgun which I modified heavily, a Franchi Over Under 20 for sporting clays, and my pride and joy which I received as a christmas present is a Browning Citori 525 Over Under Limited Edition Aunheiser Bush/Budweiser 28 gauge #73 of 300 made.
I'd have to say my Kimber Compact in stainless is my favorite 2010 purchase. It's been flawless and with a bit of polish on the slide and some nice grips is gorgeous. After that would be my Sig P238. It's fun to shoot and goes with me everywhere either as a primary gun in gun intolerant environments or as my BUG.
Traded a rifle I had $400 in for a DPMS Sportical. I figured it would be lower quality, but have really enjoyed shooting it and have had no malfunctions. Sorry, no pics yet.
Best deal I got in 2010 was my stainless Colt King Cobra. I only paid $525 for it. No box or paperwork, but I plan on using it as a shooter anyway. The action is almost a clean as my PC S&W. So far I've been able to keep the wife from taking it.
Sorry the picture stinks. Too cold to photograph outside.
