Referring back to TTSHs' post #18,I wish I was able to 'write' something up. But I'm a 'newbie' when it comes to 3rd gens(and/or 1st & 2nd gens).
I've had a 1006 since the early 90s' and added a CS9 sometime after that. I didn't start pursueing 3rd gen pistols until the end of 2012. Since then I added a 5946,915(sold it recently),6906,6946,& 4053(for conversion to 10mm). I don't have many 3rd gen pistols.
I have a lot of magazines,hence being called 'king of 3rd gen mags'. I buy mags at gun shows(7 shows so far in 2017) and watch the firearms forums for those wanting/needing mags. I sell for $5 over what I paid + USPS postage. I probably shipped about a dozen 10mm mags around the country,the 10caps go to California,others scattered around elsewhere. I have 45 mags and don't own a 45,I have 40 double stackers and don't own a gun for them. I try to maintain a variety. I'm still learning about the various varieties.
