I'd like to hear peoples opinions on this.

A) 20ips is actually quite fast.
B) Yes, your mechanism should NOT allow the cylinder piston itself to be the stop. That can break the cylinder. Add an external stop, JUST before the stroke causes the piston disc to hit its end plate.
C) IMO, another solution is to just to
- use the cylinder to "[MaleChicken] a spring" to a catch (the CDF editor won't let me use the "Naughty Word" term! <lol>).
- disengage / back the cylinder off to its Rest Position.
- NOW release the spring with a second tiny cylinder (or other device), by pulling a pin.
A bit more fab and a control ritual, but it saves a LOT of wear and tear on your cylinder because it is not DIRECTLY involved in the firing of the device itself anymore.
