As the thread name, is there any reason why the Custom Grip modification is harder to find than Recoil Gloves?
Short answer seems no, and the benefits each apply do not appear to be taken into consideration with each other when their availibilites were calculated.
Recoil Gloves weigh 1kg, have a +0 Avl, and remove the -20 modifier when firing Basic weapons with one hand.
The Custom Grip weapon modification adds 1kg to the weapons weight, has a -10 Avl, consumes the weapons only modification slot, and removes the -20 modifier when firing Basic weapons with one hand.
In other words, they do the same thing, but one is categorically worse than the other, but has a higher cost.
Its worth noting that in the DH1 errata, Recoil Gloves had their availability of Common set to Rare. I think this is relevant here as well. Personally I could see -30 working with Recoil Gloves.
And not to muddy this topic too much, but what are peoples thoughts on the dual wielding of Basic weapons? As far as I can tell, nothing forbids it. A pair of Storm Bolters with Targeters and Amputator Shells, weilded in both hands via Recoil Gloves, benefitting from Gunslinger and the Desperado/Hive World/Ministorum bonus ability is rather frightening. Certainly they ate it with regards to the difficulty of the acquisition tests involved, but still, this is almost pure equipment alone, little XP spent, and the character can take on some significant challenges (assuming they can get initiative and pass the fear related issues).
EDIT:
To expand upon the above example, It will take a bare minimum of 1200 XP to arrive at, assuming a starting BS of 40. Any less BS will take more XP as a result of needing more ranks to buy necessary advances.
-Ballistic Skill Advance + 5 - 200XP
-Gunslinger - 600XP
-Weapon Training(Bolt) - 400 XP
With just those things, if the above character (Hive World/Ministorum/Desperado, e.g. a 40k version of Monsignor Martinez from King of the Hill) got his hands on a pair of Storm Bolters (-40 Avl), 2 Targeters (-20 Avl), Amputator Shells(-30 Avl) and 2 Recoil Gloves (+0 Avl), then, on his round in combat (likely earlier than others with Hive Worlds +2 to initiative):
1-2 AP on Aim (1 if an Evasion is needed later, otherwise 2, as that greatly increases the lethality)
1 AP Shoot at RoA 2 with the first Storm bolter. Spend a fate point to get +30 on the check (ministorum bonus). With 45BS, this comes out to be a check on BS 85-95 (45 + 30 + 20 from aiming). A likely hit. The targeter imposes a -20 on Evasion. Storm doubles DoSs on the attack. In other words, highly unlikely the target will dodge. Score hits.
1 AP Shoot at RoA 2 with the other Storm Bolter. Since the first most likely hit, benefit from Desperado bonus (+20 to second attack). If another fate point available spend that as well. Another BS 95 test then. With hits scored from first attack, likely to deal severe damage/kill on this attack.
Sadly, I know this is all theory crafting, and serves little actual purpose in a discussion, but its interesting to see how much of the system is weighted towards gear than character skill.
