Hello-I am shopping for a Ruger SA hand gun in 45LC. I want one with the Bisley grip since rumor has it they handle recoil in a more comfortable fashion . The question is "how do I identify a Ruger with the Bisley grip. Is the handgun identified as a Bisley model. Do they still make this model or would I have to buy used. Thanks for any info since I am a nebie on this Ruger stuff.
