BudsGunShop.com - Does it have the new slide release control?

Sig has been using the smaller (newer) slide release for quite a while now, I don't think you'd get one with the older style. You could always refuse the transfer and return it if you did get the older style, but I'm confident you won't.

It should however there is always a chance that you happen to get a older gun with the old style I suggest that you Contact Buds customer service (859) 368-0371 available 9AM to 9PM CST Monday through Fridayor use the blue chat now button and they will help you We are not buds employees we are volunteers that answer questions
