Who makes a good flush "buttplug" for the glock 27 that doesn't require any mods to the gun itself? that I can just pop in and not worry about?

Get the Jenta plug for the G27.
I drilled a hole in mine to make it accept a Deep6Com plug,it works well,but the Jenta plugs work better,no drilling necessary.

Ok cool, because I cannot modify any weapon I plan on using on duty.

I have one for my Glock 22 (duty weapon) but it isn't flush, it sticks out, so as to fill that gap between the backstrap and the magazine I suppose, ugly in my opinion....but I'll replace that soon too...

Now if you try and plug your G22 the Deep6con is the right plug for that size.I have them on my G22 and G22c.
Check with your agency about the policy regarding plugging your Glocks.Some agencies frown on them for cleaning porpouses and the fear for operational function.
The G27 didn't have the lanyard loop hole like the G22 has and I drilled my G27 to make so it could accept the Deep6con plug which had the nub.
