Just purchased my first gun! Ruger SP101. I put 38 specials through it a few days ago and was extremely pleased with how much control I had over the recoil (such a heavy barrel helps). But tonight I put the intended 357s through it and ...a.whoa... Not once did I feel like I had control over that thing. I know Ruger says that using 38 specials is fine but I would like to hear from the peanut gallery
