Like others on the forum, I own several Sigs and I like them all. I recently purchased a 239 .40 through the LEO program and like it fine, although the factory installed SRT didn't work like it should and the Nitron had some pin holes in places. I called, they sent a prepaid label and I sent it back. 8 days later here it came on the Fedex truck, perfect. I couldn't do the Nitron but as a certified armorer I could probably have fixed the SRT but thought, "that's why there's a lifetime guarrantee." Before I bought my R9S stealth I considered a 290. Because I could get LEO pricing on it, I considered it hard. But I ended up ordering another R9S stealth for my son as a gift instead and Tom Watson handled it for me.
There were a couple of reasons. First I didn't need another weapon that only fit in between the R9S and my other primary carry weapons i.e. a Colt Defender .45 and a Sig 239 .40. The R9S fills all roles not covered by the other two. The 290 is several ounces larger than the R9S so I gain nothing except more size. Finally, for all the good feelings that I have for SIG, their foray into the world of polymer frames have met with mixed results. Unlike HK who has been totally sucessful with Polymers, SIG has not. So the jury is still out on how they are dealing with it. I have a few HK's and like them a lot. But I dislike the fact that any problem with the polymer frame and the rails molded in and it's off to HK you go. There is no other fix. With a SIG, alloy frame, barring a crack, I can fix it, most likely. If it's a Colt I can fix it even if it does crack. So the 290 just wasn't for me. But I think it could be a real answer for some. Especially those who feel the need for slide stops, hold open devices and magazine releases that aren't on the butt, and most especially for those who feel they need lots of practice with any weapon. Most of us realize that the Rohrbaugh was not intended to be beat to death on the range. You familiarize, get comfortable, check reliability, and take it out once in a blue moon to recheck. But you don't sit there and run hundreds through at every possible range session. It simply wasn't designed for that. To paraphrase Patrick Henry, " I know not what course others may take, but as for me," I'll stick with the Rohrbaugh.
