Hello my fellow XDrs. I need some advice. I have a XDm 9MM and a XD40 service and I shoot a lot of USPSA\IDPA. With the price and shortage of 9mm\40S&W ammo, I'm looking for a .22lr solution. I did some research and the Sig P226 USPSA or Blackwater models caught my eye. I especially like the .22lr conversion system i can buy as an add on. With that being said I have a few questions: 1. Is there a .22lr conversion anywhere for the XD or XDm. I am 99% sure there isn't but i have to ask. I know I could move to Glock but I owned Glocks before and they just didn't work for me. Nothing against them but the sight picture and grip angle drove me crazy. 2. I know a lot of guys in the blogs own Sig's as well. What are you guys thought on the Sig P226 or P220. I have shot and carry the P229 for work. I'm in the Coast Guard. So I like the Sig but as soon as I get in the truck out comes the XD. I want to know about carrying the Sig 24/7. Is it easy to conceal, are there any problems with heat in the summer time. General information like that would be nice. 3. Is there any other pistol/.22lr combos out there that any of you use to keep in practice with? Thanks in advance for the help.
