Congrats on the XSE I like everything about mine ( a pre dove tail sight .45 ) except the duck butt grip safety which i will replace with a wilson or something eventually .
As to your question I also would go with the Sparks of the holsters you have listed since i am neither modern nor open minded enough to appreciate a tupperware holster no matter how well made .... If you can get the sparks over the counter go for it , if not check out some other makers such as K&D ( i buy from them ) UBG which i have not tried but gets good reviews with short wait times , ect.. I will link you to another forum here which has some stickys that may intrest you on holster makers quality , wait times , and customer service , now note that some of the posts are what you expect from the internet on the complaint threads , but some have valid points . I am not sure if you need to register to see the link , but if you do register you wont be spammed ect..

The only thing i will add and i say this because i dont know what your ccw experience is .. The holster is part of a carry system , and if you do not have a real gunbelt then buy a belt with the holster and have the loops sized to the belt . You need a stiff belt ( stiff is defined as the belt will not " roll up when worn , it maintains its full width and likely is contoured so when laid flat it resembles the smile in a smiley face instead of a straight line . That coupled with loops that fit will anchor the pistol where you put it and not allow it to shift . This is important for the draw , but that is over hyped IMHO. Where i find it to be most important ( especially with heavy all steel guns like the 1911 , hp , p7 hk , ect.. ) is for comfort and security . With a wall mart belt ( even right sized ) a heavy gun is literally a pain to carry all day every day . With a good belt it is much more comfortable .
Food for thought if you havent thought about it , or if you ( or readers of the thread ) are inexperienced .
