[Who makes this Guide Rod? CZ75 TS]

Just picked up a used CZ75 TS .40 and

found this guide rod installed.

I know it's not the stock one, but

not sure who makes this one, any guess? Sprinco?

Also makes it pretty tough to rack, guess I'll see how it shoots.

[drills involving moving (live fire)]

I've pretty much assembled a 3-ring notebook of live fire (static) drills to practice, but have

very little on drills involving movement or drills with different shooting positions.

Currently using drills like.......

pos.A fire 2 T1, move lateral (15'-20') to pos.B fire 2 T2, L to R & R to L

pos.A move lateral (15'-20') to pos.B, 6 rnds on the move, L to R & R to L

shoot while advancing 6 rnds T1 30' - 15'

shoot while retreating 6 rnds T1 15' -> 30'

Just wondering if anyone has some suggestions for other drills they use or

standard type drills involving moving?

Thanks,

[Training Drills at Indoor range]

New guy here..... I shoot outdoors, but some times stop at the indoor range for a quickie or to test some change on the gun, etc.

Play with the targets a little bit, I find the following helpfull and fun to represent hard cover, no shoots etc.

Try folding the targets over and taping them on their selves. As below.........
