I have gen2 TX22 4.6" bbl TORO with Sparrow and FFT frt. Unsuppresed it ran great with regular loads. Didn't try subs unsuppressed.
Suppressed no go with any ammo I tried.

I modified the galloway precision optic mount plate by filling the voids with cerrosafe. The modified plate 35g plus optic 30g repaces the TORO blank cover 19g for net weight gain of 46-47g/1.6oz
Slide with this setup is 150g without barrel/spring assembly vs 103g without optic/galloway mount.
CCI 40gn subs no go
Rem Thunderbolt 40gn 1255fps - good to go
Fed 38gn 1260fps - good to go
Fed 36gn white box fps not listed - good to go
Cheap postal scale used for all weights.
The optic may not be very practical on this gun but won't be confused with a switch.
I'm pleased with resuls.
