Im not the best person to ask on prices, but that ought to be a fair price - new price at the moment is around £175
Important thing to highlight though - add a lanyard - you don't want to be looking in bushes at the end of the day when you realise its not there any more
Regarding holsters - I'm picky on these. You will need one if carrying as a sidearm, and you don't want it to be in the way or uncomfortable
Some people like drop leg holsters, im not keen as it puts the weight on your leg, and if its not solid then you not only have a weight on your leg but a loose flapping weight on your leg
I picked up the Tipmann holster, I was not so sure about it but when i tried it out it is well designed and can be switched to various configurations I removed the drop leg element and directly belt mounted it
When i have the 13ci cylinder mounted its not holsterable so I either use a bag, my trouser pocket or keep it in my hand
