Its basically just to save time when cleaning thats all, with the speed strip you unscrew the allen screw and pull out the bolt thats it, reverse to reassemble the pistol.
The thing with my pistol is removing and replacing the barrel/receiver assembly it is an extremly tight fit, you have to wack the hell out of the rear of the barrel to get it off.
My wifes pistol on the other hand isn't that tight. Otherwise I can disassamble it in my sleep.. To install it should take no more than half an hour, as long as you know how to take the hammer and all out, which I do.
