Feel the Pain! Be one with the Pain!
I love my 342. Maybe it's just me and my shooting style, but I find it to have a more manageable recoil than the all steel model 36 I carried for years. Yes, the light weight makes for quite a kick, but
because of the light weight the recoil seems to go away as quickly as it comes. I'd call it more of a "snappy" recoil rather than a heavy recoil. This is only with +P ammo by the way... Standard loads aren't a problem at all.
A day at the range
will leave you with that "just used the weedeater" feeling in your hands, but a self-defense situation isn't a day at the range. If you need to fire 50-100 rounds at a BG, you brought the wrong gun anyway.
For me, a sharp recoil is a reasonable trade-off for the ultra-light weight. It makes carrying a pleasure rather than a challenge.
Good luck with your decision.
