Being a Ruger owner myself, congratulations on choosing SR45. I have the SR9 and have owned it since early in 2010. I bought mine because it is American made and tried most of the popular guns like Glock, Taurus. Sig, & Beretta, and like the fit and feel of the Ruger more. I just felt right I guess you'd say. I carry all day everyday and have both a DECCE and PA. Non-Resident Permit. Holster wise I bought a Deep Comfort Pro-Carry IWB from
www.theholsterstore.com in Florida. They make their own holsters here in the USA and of USA materials. They had good prices and when I ordered I received it in 4 days.
Hope you have many years of safety and enjoyment with your SR45. Wise Choice.
