I picked up the Tac 4 yesterday and shot it at the range and I really, really, hate it!

Seriously, I really like it and I think it will rotate with Glock 30 as my primary carry gun. But the gun did come without some "issues" though. The prior owner decided to glue a tac rail to the dust cover. The sight of that did not go well with me, but I thought the gun was still worth the price I paid for it. As far as shooting performance, my groups were very tight at 7 yds.
The gun has ambidextrous safeties and really nice grips, which I think these are after market. I do plan to buy extra 13 round mags.
Do any of you have some suggestions for a good holster?
I am trying to figure out how hold it is. I looked at the extractor and it appears to be much bigger than the extractor on my Springfield 1911. The box it came in stated it was made in Canada and the box has black lid with a white sides and bottom. Does anyone have an idea about how old it might be?
Between Tom Gresham and Michael B, I think they have sold more guns than anyone in history, well maybe short of arms dealers to the Third World.

Thanks to all for your help! DRTV is a great resource!!!
