I have had a micro squall and personally I would probably choose something besides it. They are darned heavy for one thing, and if you dont like the sheridan frame a .45 frame conversion costs a lot of money.
The t8 would be handy because reloading is all 1 action, insert a magazine. It means you arent remembering when you need to change 12 gram, in relationship to when you need to reload.
For long games the t8 might not be the best, but for anything reasonable they seem to make a lot of sense.
PMI USP's are good for a cheap blowback and piranha parts are common as can be.

PSA: Please don't use photobucket to post images. When you go through one of the older picture threads and find a lot of dead photo links, it is because of photobucket. They limit the amount of bandwidth your free subscription pictures can use, and then make the photo unviewable. Please use imgur.com or another free image host that does not ruin picture threads.
