Beretta has a Stinger, legal for production class, that is available on their web site. It's a little pricey, but it's all I can find to fit my 92A1.

I got a great deal on a new SPS varmint a while ago and brought it to Duffy's a few weeks ago. John (I think) the smith there did a great job cutting the barrel to 22" and re crowning (very detailed crown), lapping the lugs, and setting the barrel back. I also put it in a B&C Medalist...
I vote to keep that one stock. If you want to pimp one out, buy a 6920 or a BCM, but you're not allowed to trade that one in! It's a classic. Nice gun.
I'm new to this forum (I post on M4carbine and Berettaforum) but me and two buddies sent in our application yesterday. If it gets in in time, we'll be shooting this match. Hope to meet you guys there!
