Back around 1998 or so I had the opportunity to pick up A SIG P210 for a very good price.
I have been described by close friends as being 'Not that stupid...usually.." so I jumped on the gun.
Now this gun can be fitted with a pretty nifty .22 kit. I had the opportunity to buy one with the gun at that time ($400 for the top end, 2 mags, and carrying case).
I didn't buy it.
Every other year I'd see one of these set ups. And every other year I'd say "Next year."
Years pass. I see one at a shooting event, a couple of months ago...Nifty!!
So, I decided I had to have one.
The prices for the kit? Anywhere from $2400 to $1800....For used.
The moral? Don't wait. Especially if it's something you need or really want.
