Along with speedloaders, there's another product of possible interest to 617 owners, the 10-round .22 rimfire "speedstrip" offered by Tuff Products. A few years ago, I tried to order their .44 Mag speed strips from their website, which had some glitch that foiled my on-line order attempt, so, I phoned them instead, and ended up having a chat with the owner. Turned out we had some acquaintances in common, and, one thing leading to another, he asked for product suggestions, and among mine was the above-mentioned .22 strip. While we were talking, he asked where he might find the correct spec for center-to-center chamber spacing. I happened to have a 617 at hand, measured it, and gave him the critical dimensions to fabricate the mould, and now, there you have it! These are great --- slip a couple, almost unnoticed into shirt pocket, or the accessory pocket in a Wilderness Safepacker holster, into the watchpocket of your jeans, or into Tuff's belt pouch.
