1st choice- Ruger SP 101 .357 mag.
2nd choice- Glock 26 or 27 (usually it's the .40 over the 9mm)
Inside the waistband or outside depends on what pants or jeans I'm wearing, I prefer outside the waistband.
1st-choice now is my new XD45
with Federal Hydra-Shok 230gr. JHP
2nd-choice now is my new XD45
I've retired the Ruger SP101 and both Glocks. The XD45 is a little larger then I'm used to, especially the longer grip but with the right holster (IWB or OWB) it should work out just fine. Right now I'm waiting on a Galco OWB.
