Don't have pics handy of the one or even made of the other right now, but I have two 22LR pistols that I like VERY much.
One is a Buckmark Hunter with the long barrel (7.25")
http://www.browning.com/products/catalog/firearms/detail.asp?fid=006B&cid=051&tid=403 I put a Bushnell TRS-25 RDS on it. Everyone who picks it up loves it, and it's a laser even for so-so shooters. The wood grips feel great. Trigger is great out of the box, though there is a spring flip mod that is reputed to lower the pull even more; I have not done that yet as I'm having too much fun with it as-is.
The other is a Colt/Umarex 1911 rail gun
http://www.waltherarms.com/products/tactical-rimfire-replicas/government-1911-a1-rail-gun/ I'm a 1911 fan (though I have other stuff also). I debated long and hard between this and the GSG version. I've held both; both feel fine to me. The finish on the GSG ones that I've seen seems to wear easily, though I have not seen many of the Sig ones that have been around a while. I don't care about the rail, but I wanted those particular sights since they match what I usually carry. It is not broken in well at all yet, and I've put most Rem Golden Bullets through it (for break in

), so the accuracy is not quite up to par yet. It also needs a bit of trigger TLC, but I need to finish break-in first.
I say that about the accuracy because I used to have a Sig Mosquito. Some folks have reported issues. I had none with mine - I really enjoyed that pistol. It was super easy to strip and clean. Yes, early on I had about 30% FTE with non-Minimags ammo, but Minimags were fine in it - just like the manual said. Yes, it's made of Zamak and not steel. But it was SCARY accurate. One time I put the contents of a 10-round mag inside one of the 1.5" black circles on those targets at PDHSC that has a mix of small black circles and larger blue, green, and red circles...at 25 yards, two-handed grip, standing. I was shocked, given the long trigger pull. If you like Sigs, it's a decent choice in my book. I'm not a Sig person and I prefer the 1911 platform, so I traded it in. I wanted the rail gun worse...I have several 1911s in 45ACP, and one in 9mm; since it's my platform of choice, I wanted a 22LR also, with the same ergonomics.
I had a S&W 617-2 6-shot revolver with 6" barrel for a while. It was gorgeous, but I'm just not that big of a revolver guy, so I traded it in too, on something else I wanted more.
Hope all this rambling helps!
