Yes, they seem to be hard to find these days.
I have one with No ILS ( it seems to be plugged up)
but I have two keys, and it does have the mag safety.
12 rounds of factory ammo through it.
2 new 15 shot 357/40 mags, one still in the box.
I'm on fence on whether to sell it or not as my Glock 33
is much smaller and lighter.
However, I'd want to sell it with the 2 mags, and that might be hard to do.
Will probably wait until after April to sell it and my NIB Glock 31, when people have the tax returns coming in .
I just like the smaller guns these days.
Best of luck with your eventual 357C purchase.
