The X series are for aircraft riveting and there is nothing wrong with them. They give a known impact to properly set aluminum rivets. The guys who do aircraft have rules on how they have to set a rivet. They have a 1/2" piston if I remember correctly and the number before the X relates to the length it moves.
With aluminum rivets they work harden quick and take time to reach full hardness depending on the type of aluminum or something like that. I do not have an A&P, just work close with guys often building aircraft stuff.

The thing to look for at flea markets are the longer barrel air hammers. The automotive long throw air hammers have more energy per hit. They seem to use a 5/8" piston and different length barrels. They can work with more authority and do well on freeing very stuck parts.

Typically either type of gun can be pricey. But sometimes you luck out if you know what your are looking at as I have stumbled into a few real real cheap at garage sales and local flea markets.
