    I am wondering if anyone can shed any light on the Gen 4 RSAs vs. the Gen 3. On the Gen 3 there was one part number for the G17, G22 and G37 (same RSA used in all three). For the Gen 4 there is one RSA for the G17 and another for the G22/37. I called Glock to ask if there were different spring tensions, etc. but did not really get an answer regarding that. Does anyone know if the spring tensions are different on the Gen 4 G17 vs. G22/37 and, if so, what is the difference?

    Thanks for any info you can provide.
