Spring guide? What gun are we talking about?Thanks, for your comments. Actually, it's not reassembled, but rather placed on the spring guide and positioned under the barrel against the barrel's lug (?), or whatever you call it. However, thanks to Tanfo's assembly of the P22 (which I also have) that I watched I was able to put it back together. Little hard to hold the spring down over the guide with my "old" hands, but with a pair of gloves, believe it or not, I was able to do it. Again, thanks, for your comments.
