I was a little unsure myself about the mini until mine arrived this morning and i have gotta say i am very impressed.
i think the size will take some getting used to but despite the lack of bulk it incredibly well balanced, as strange as this sounds too i do notice there is no visible air fittings - i think these are things that will go after ive shot the marker in anger. also i dont think its a .45 frame but never the less is reasonably confortable.
Upset the neighbours out back, no kick, didnt seem particularly rough on paint(didnt break a ball going through 3 hoppers), pretty quick and again tiny!!
On the grounds ive only briefly used it, i recommend it
Speak to the lads from Storm, theyve only just gone over to them from Timmies, think Bolter was quiet impressed with his
